2% 2C3% 2C5-trihydroxyglutaric acid-4-enoic acid, this compound is in the field of organic synthesis. Common synthesis methods include the following:
###1. Glutaric acid derivatives are used as starting materials
1. ** Halogenated glutaric acid method **: Glutaric acid is first taken, and a carboxyl group of glutaric acid is converted into a halogenated carbonyl group with an appropriate halogenating agent, such as sulfoxide chloride and phosphorus tribromide. If glutaric acid is reacted with sulfoxide chloride, glutaric acid monoyl chloride can be obtained. After that, it is hydroxylated by a suitable hydroxylating agent, such as sodium hydroxide aqueous solution, at a specific temperature and reaction time, and a hydroxyl group is introduced at a specific position. After elimination reaction, such as heating in a basic alcohol solution, the halogen atom is removed from the adjacent hydrogen atom to form a double bond, thereby constructing the basic carbon frame and functional group structure of 2,3,5-trihydroxyglutaric acid-4-enoic acid.
2. ** Glutaric anhydride method **: Glutaric acid generates glutaric acid anhydride under the action of dehydrating agent, and the carbonyl group of glutaric acid anhydride is attacked by nucleophiles, and hydroxyl groups can be introduced. For example, nucleophiles such as sodium alcohol are reacted with glutaric acid anhydride and then hydrolyzed, hydroxyl groups can be introduced into the glutaric acid anhydride structure. By controlling the reaction conditions and the amount of reagents, hydroxyl groups can be introduced at different positions, and then the target product can be synthesized by subsequent reactions such as elimination and oxidation.
####II. Construction of
1 through carbon chain growth reaction. ** Diethyl malonate method **: With diethyl malonate as the starting material, first alkylation with appropriate halogenated hydrocarbons to increase the carbon chain. For example, reaction with halogenated ethanol under basic conditions to generate the corresponding alkylated diethyl malonate derivative. Then through hydrolysis and decarboxylation reactions, a carboxylic acid containing hydroxyl groups is formed. After that, the structure of 2,3,5-trihydroxyglutaric acid-4-enoic acid is gradually constructed by using oxidation, elimination and other reactions to adjust the functional groups and introduce double bonds at suitable positions.
2. ** Grignard reagent method **: Select suitable halogenated hydrocarbons to make Grignard reagent. For example, Grignard reagent is made from bromoethanol, which reacts with carbonyl compounds, such as ethyl pyruvate, to increase the carbon chain and introduce hydroxyl groups. After a series of reactions such as hydrolysis and oxidation, a carboxylic acid with a target structure can be constructed. After elimination reaction, a double bond is formed to complete the synthesis of 2,3,5-trihydroxyglutaric acid-4-enoic acid.
All of the above methods of synthesis have their own advantages and disadvantages, depending on the actual situation, such as the availability of raw materials, the difficulty of reaction conditions, and the purity requirements of the target product.

2% 2C3% 2C5-trifluoropyridine-4-carboxylic acid is a kind of organic compound. Its physical and chemical properties are quite specific.
Looking at its physical properties, under room temperature, it is mostly white to light yellow solid form. This is due to the orderly arrangement of molecular structures and the mutual force. Its melting point and boiling point also have specific values due to the chemical bonds within the molecule and the forces between molecules. The melting point is about [specific value]. At this time, the thermal motion of the molecule is sufficient to overcome the lattice energy and cause the solid state to turn into a liquid state. The boiling point is related to the energy required for the molecule to break free from the liquid phase. Under specific pressure, it can reach [specific value].
In terms of solubility, the substance has a certain solubility in organic solvents such as ethanol and dichloromethane. This is because the molecules of the organic solvent and 2% 2C3% 2C5-trifluoropyridine-4-carboxylic acid molecules can form interactions such as hydrogen bonds, van der Waals forces, etc., which help them disperse in the solvent. However, the solubility in water is relatively limited, because the polarity of the molecule and the polarity of the water molecule are not perfectly matched, resulting in weak interaction between the two.
In terms of its chemical properties, the chemical activity is considerable because it contains carboxyl groups and pyridine rings. Carboxyl groups can participate in esterification reactions, and alcohols can be catalyzed by acids to form corresponding esters. This reaction is reversible and follows the principle of chemical equilibrium. The nitrogen atom on the pyridine ring has a lone pair of electrons and is basic, which can neutralize with acids to form pyridine salts. And the electron cloud distribution characteristics of the pyridine ring enable it to undergo electrophilic substitution reactions. Under appropriate conditions, halogenation, nitrification and other reactions can occur, providing rich possibilities for organic synthesis.
In summary, 2% 2C3% 2C5-trifluoropyridine-4-carboxylic acid has important application value in organic synthesis, medicinal chemistry and other fields due to its unique physical and chemical properties.

Today, there are 2,3,5-trifluoropyridine-4-carboxylic acids on the market. What is the price of this drug? In the field of chemical industry, it has a wide range of uses, and its price range depends on many factors.
First, it depends on the level of purity. If the purity is very high, almost extreme, and there are very few impurities, the price will be very high. Cover high-purity things, the preparation is difficult, the process is complicated, and it requires exquisite methods and high-quality materials, so its price is high, or it can reach hundreds of gold per gram.
Second, it depends on the amount of production. If this product is produced in large quantities and the market supply is sufficient, according to the principle of supply and demand, the price may be flat. On the contrary, if the output is scarce and the supply is in short supply, the price will rise.
Third, the price of raw materials also affects. If the raw material for preparing this acid is high and difficult to find, the price of the finished product will also rise.
Fourth, the state of market competition cannot be ignored. If the competition in the same industry is fierce, in order to compete for market share, merchants may lower their prices to attract customers.
Roughly speaking, the price of 2,3,5-trifluoropyridine-4-carboxylic acid is in the range of tens of gold to hundreds of gold per gram. However, this is only an approximate number. Market conditions are volatile, and prices also move. To know the exact price, consult the chemical market merchants to obtain an accurate number.
