179923-32-1 - Introduction
2,3,4, acid is an organic compound with the chemical formula C6H3BF4COOH. The following is a description of its nature, use, preparation and safety information:
Nature:
2,3,4, acid is a solid white crystal, insoluble in water, soluble in organic solvents such as alcohols, ethers, etc. It is a weak acid that reacts with a base to form the corresponding sodium or ammonium salt.
Use:
2,3,4, acid is mainly used as a catalyst, complexing agent and starting material for organic synthesis. It is often used in organic synthesis to synthesize compounds containing boronic acid structures and can be used to synthesize other chemicals. In addition, it is also used in optical materials, optoelectronic devices and other fields.
Method: The preparation method of
2,3,4, acid is mainly obtained by the reaction of borate ester with halogenated substituted benzene. The specific steps are as follows:
1. Boric acid esters are reacted with halogenated substituted benzene in an organic solvent.
2. After the reaction is complete, 2,3,4, acid is obtained by solvent evaporation or crystallization.
Safety Information:
Under normal use and operating conditions, 2,3,4, acid is relatively safe. However, the following safety measures should be taken:
1. Avoid inhaling dust or contact with skin, eyes and mucous membranes. Appropriate personal protective equipment such as chemical goggles, gloves and laboratory coats should be worn.
2. During the operation, ensure good ventilation to avoid dust to reduce the risk of inhalation.
3. Follow proper handling and storage methods and avoid mixing with other chemicals to prevent fire or explosion.
4. If inhaled or exposed to the compound, wash the affected area immediately and seek medical help if necessary.
