Compounds with 2-% hydroxyl-4-to-their carboxyl groups have the following physical properties:
This substance is mostly solid at room temperature, but some of the specific structures are liquids. Its melting point varies depending on the specific molecular structure. Generally speaking, those with strong intermolecular forces and regular structures have higher melting points; vice versa. For example, such compounds with longer carbon chains and relatively symmetrical structures have melting points of up to tens of degrees Celsius, while those with looser structures and shorter carbon chains may have melting points close to or below room temperature. In terms of boiling point, the boiling point of
is generally higher because the molecules contain hydroxyl and carboxyl groups, which can form hydrogen bonds, resulting in enhanced intermolecular forces. The existence of such hydrogen bonds makes the molecules need more energy to break free from each other and boil. The specific boiling point value is also affected by the molecular structure, and the boiling point of complex structures may reach hundreds of degrees Celsius.
In terms of solubility, compounds with 2-hydroxy-4-carboxyl groups have a certain solubility in water due to their hydrophilic hydroxyl and carboxyl groups. Hydroxy and carboxyl groups can form hydrogen bonds with water molecules to enhance their dispersion in water. However, with the growth of the carbon chain, the hydrophobic effect is enhanced, and the solubility will gradually decrease. In organic solvents, its solubility also varies depending on the properties of the solvent. Polar organic solvents such as ethanol and acetone have better solubility to such compounds. Due to the principle of similar dissolution, the interaction between polar molecules is conducive to dissolution; while in non-polar solvents such as n-hexane, the solubility is poor.
In appearance, pure such compounds are usually colorless or white, but if they contain impurities or specific substituents, or show other colors. Most are crystalline, and the crystalline morphology is dominated by molecular arrangement and lattice structure, or is needle-like or flake-like.
The density is usually similar to or slightly higher than that of water, and the specific value varies depending on the precise structure and constituent elements of the compound. Under certain conditions, its density may change with factors such as temperature and pressure.

2-Amino-4-pentenoic acid is an organic compound with unique chemical properties. In this substance, the amino group is basic and can react with acids to form corresponding salts. For example, if it encounters hydrochloric acid, the nitrogen atom in the amino group will use its lone pair of electrons to accept the hydrogen ions dissociated by hydrochloric acid, thereby generating positively charged ammonium ions, and chloride ions combine with it to achieve acid-base neutralization.
The carbon-carbon double bond in its molecule gives it unsaturation and can carry out addition reactions. Like in the presence of a suitable catalyst, an addition reaction can occur with hydrogen, one of the carbon-carbon double bonds is broken, and two hydrogen atoms are added to the two carbon atoms of the double bond, and then converted into a saturated alkane structure; it can also be added with halogen elements, such as bromine elements, and the two bromine atoms in the bromine molecule are respectively connected to the two carbon atoms of the double bond to form halogenated hydrocarbons.
In addition, carboxyl groups are acidic and can be neutralized with bases, such as with sodium hydroxide. The hydrogen ions in the carboxyl group will combine with hydroxide ions to form water and form corresponding carboxylate salts. Moreover, the carboxyl group can also participate in the esterification reaction. Under the condition of concentrated sulfuric acid as a catalyst and heating, it reacts with alcohols to remove the hydroxyl group of the carboxyl group and the hydrogen atom of the alcohol, and the two combine to form esters and water.
2-amino-4-pentenoic acid shows a variety of chemical activities due to its functional groups such as amino groups, carbon-carbon double bonds and carboxyl groups, and can participate in many types of chemical reactions. It plays an important role in organic synthesis and biochemistry.

The synthesis method of 2-% hydroxy-4-pentenoic acid has existed in ancient times, and it has evolved over time, and there are many changes. The following is your detailed description.
Early synthesis of this acid, often using natural products as starting materials, is obtained by subtle chemical reactions. For example, compounds with similar structures can be found from some plant extracts, and then through several steps of reaction and gradual modification, the final product is 2-% hydroxy-4-pentenoic acid. Although this route is a natural raw material, the extraction process is complicated, and the yield is quite limited by the source and content of the raw materials, making it difficult to prepare on a large scale.
Later, chemical synthesis methods gradually emerged. Using common organic compounds as starting materials, after ingenious design, various chemical reactions are used to construct target molecules. For example, using acrylate compounds as starting materials, an addition reaction occurs with suitable reagents, a hydroxyl-related group is introduced, and then a series of reactions such as hydrolysis and rearrangement can be performed to obtain 2-% hydroxy-4-pentenoic acid. Although this method gets rid of dependence on natural products, there are many reaction steps, complicated operation, and some reaction conditions are harsh, which requires precise control, otherwise it is easy to produce side reactions and affect the purity and yield of the product.
This acid is also synthesized by microbial fermentation. Screen specific microbial strains, and under suitable culture conditions, make them convert simple carbon sources, nitrogen sources and other nutrients into 2-% hydroxy-4-pentenoic acid through their own metabolic pathways. This method is green and environmentally friendly, and the reaction conditions are mild. However, the microbial culture process needs to be carefully controlled, and the selection and optimization of strains are time-consuming and laborious, and the fermentation cycle is relatively long.
Another method of photocatalytic synthesis has emerged. By using photocatalysts to absorb specific wavelengths of light, active species are produced, which initiate chemical reactions and promote the conversion of substrates into target products. This method has mild reaction conditions and good selectivity, and is expected to open up a new path for the synthesis of 2-% hydroxy-4-pentenoic acid. However, it is still in the research stage, and many technical details still need to be improved.
All these synthetic methods have their own advantages and disadvantages. In practical application, it is necessary to weigh the cost, yield, purity, environmental protection and many other factors according to specific needs, and make careful choices to achieve the best synthetic effect.

Nowadays, there is 2-amino-4-nitrobenzoic acid, which is difficult to determine the price range in the market. Its price often varies due to many factors, such as the supply and demand of the market, the quality of quality, the source of production and the cost of production.
Looking at the market conditions, if it is of high quality and refined, the price will be very high. In today's chemical industry, the demand is complex. Such compounds are either used in the production of medicine or in the production of color, and the demand varies from time to time. If the pharmaceutical company is very eager, and there are few producers, the price will rise; on the contrary, if the supply exceeds the demand, the price will decline.
And the difference in origin is also related to the price. For those who are transported from afar, the price may be higher than that produced nearby due to the burden of travel expenses. And different production methods have different costs, which can also cause changes in prices. If the new production method can save materials and time, and reduce its cost, the price may be close to the people; if the cost of the old method is high, the price is also high.
Roughly speaking, its price in the market ranges from hundreds to thousands of yuan per kilogram. This is only an approximate number, and the actual price depends on the specific market conditions at the moment, and cannot be generalized.
