The physical properties of 2-hydroxybutyric acid, 3,5-dihydroxy- are as follows:
This substance is mostly colorless to light yellow viscous liquid at room temperature, with a slight odor. Its melting point varies depending on the specific structure and purity, and is roughly in a relatively low range. It can solidify into a solid under certain conditions. The boiling point is relatively high, and a higher temperature is required to turn it into a gaseous state.
In terms of solubility, it is easily soluble in water, which is due to the fact that the hydroxyl group and water molecules in its molecular structure can form hydrogen bonds. With this strong interaction, it can be miscible with water in any ratio. At the same time, some polar organic solvents, such as ethanol, acetone, etc., also show good solubility and can be uniformly mixed with these solvents to form a stable solution.
The density is slightly higher than that of water, and it will sink to the bottom after mixing with water. Its viscosity is higher than that of common small molecule solvents. This is due to the strong hydrogen bond interaction between molecules, resulting in increased friction between molecules and increased resistance during flow.
In terms of optical properties, if the molecular structure has a chiral center, it may have optical rotation, which can rotate the vibration plane of polarized light, and its optical rotation can be accurately determined by a polarimeter.
In terms of odor and appearance, the colorless to light yellow appearance makes it visually clear, and the slightly special odor is due to the molecular structure. The odor is not strong and pungent, but has a certain uniqueness. The odor intensity and specific characteristics will vary slightly under different purity and preparation methods.

The chemical properties of 2-% hydroxybutyric acid, 3,5-dihydroxy- are quite unique and show special properties in many fields.
This compound contains hydroxyl functional groups, and the presence of hydroxyl groups endows it with significant hydrophilicity. Because its hydroxyl groups can form hydrogen bonds with water molecules, it has a certain solubility in water, which makes it potential for application in some systems that need to function in an aqueous environment.
From the perspective of reactivity, hydroxyl groups have active chemical properties. It is easy to participate in esterification reactions. When it encounters carboxylic acids, under suitable catalysts and reaction conditions, hydrogen atoms in the hydroxyl group will react with the carboxylic group of the carboxylic acid to remove a molecule of water, and then form ester compounds. This reaction is widely used in the field of organic synthesis and can be used to prepare ester products with specific functions, such as certain fragrances, plasticizers, etc.
In addition, the hydroxyl groups in the compound can also participate in the oxidation reaction. Under the action of suitable oxidants, the hydroxyl groups can be oxidized to other functional groups such as aldehyde groups and carboxyl groups, thereby realizing the transformation of the structure and properties of the compound, providing rich intermediates for further organic synthesis.
At the same time, due to the existence of multiple hydroxyl groups, strong hydrogen bond interactions can be formed between molecules, which affects the physical properties of compounds, such as increasing their melting point, boiling point, etc., so that they can maintain a relatively stable solid or liquid state within a certain temperature range.
Overall, 2 -% hydroxybutyric acid, 3,5 - dihydroxy - has potential application value and research significance in many fields such as organic synthesis and materials science due to its hydrophilicity, reactivity, and intermolecular hydrogen bonding.

The production method of 2-% to its carboxylic acid, 3,5-dihydroxy- is as follows:
To obtain this compound, a suitable starting material can be obtained first, and the method of organic synthesis can be used. Common starting materials, or containing corresponding carbon skeletons and transformable functional groups.
One method can be started by aromatic hydrocarbons with suitable substituents. First, a halogenation reaction is used to introduce halogen atoms at specific positions of aromatics. This step requires the selection of appropriate halogenating reagents and reaction conditions. For example, bromine can be used. Under the catalysis of Lewis acid, the bromine atoms can be precisely positioned to the expected aromatic ring check point. < Br >
Then, through the reaction mediated by metal-organic reagents, such as Grignard reagent reaction. The halogen-containing aromatic hydrocarbons are made into Grignard reagents, and then reacted with suitable carbonyl compounds to form the required carbon-carbon bonds, while introducing potential functional groups of hydroxyl groups. This reaction needs to be carried out in a harsh environment without water and oxygen to ensure the activity of Grignard reagents.
Furthermore, the oxidation reaction of the obtained intermediate can convert specific functional groups into carboxyl groups. During the oxidation process, according to the characteristics of the substrate, a suitable oxidant can be selected. For example, Dess-Martin reagent can be used for mild oxidation conditions. If the substrate is relatively stable, strong oxidants such as potassium permanganate can also be used.
In addition, the introduction and protective modification of hydroxyl groups also need to be carefully planned. In the reaction process, if there are other sensitive functional groups, the hydroxyl groups need to be protected, and then deprotected at an appropriate stage to obtain the target 2-carboxylic acid, 3,5-dihydroxy compound. After each step of the reaction, it needs to be separated and purified, such as column chromatography, recrystallization, etc., to ensure the purity of the product, and finally obtain a pure target product.

It is difficult to determine the price range of 2% to its carboxyl group and 3,5-dihydroxyl group in the market. The price of such products often varies due to factors such as time and place, supply and demand, and quality.
In the past, these products were often expensive due to their rarity or difficulty in preparation. However, today is different from the past. With the advancement of technology, the method of preparation is gradually easier, the output also increases, and the price may drop.
When it comes to crude products, the price may be between tens and hundreds of dollars per catty. Such crude products, or containing impurities, have variable quality, and are suitable for those who do not have strict requirements for purity.
As for refined products, because of their high purity, few impurities, and wide range of uses, they are useful in various important places in medicine and chemical industry. The price is much higher than that of crude products, or to thousands of dollars per catty, or even higher.
Furthermore, the trend of supply and demand also affects its price. If there are many people seeking, but there are few producers, the price will rise; on the contrary, if there is too much demand for products, the price will be lower. And the market price in various places also varies due to logistics, taxes, etc. Therefore, if you want to know the exact price, you need to consult the local municipalities in detail, or refer to the market reports to get a more accurate number.
