Introduction
4-Chloro-2-bromobenzoic acid is also known as 4-chloro-2-bromobenzoic acid. The following is an introduction to its nature, use, manufacturing methods and safety information:
Quality:
4-Chloro-2-bromo-benzoic acid is a white crystalline solid. It has a low solubility and is almost insoluble in water, but it is soluble in organic solvents.
Use:
This compound is often used as an intermediate in organic synthesis reactions. 4-Chloro-2-bromo-benzoic acid can also be used as a dye dispersant in the dye industry.
Method:
A commonly used method for the preparation of 4-chloro-2-bromo-benzoic acid is to react 2-bromo-4-nitrobenzoic acid with nitrous acid to obtain 2-bromo-4-nitrophenol, and then the target product is obtained by reaction and treatment.
Safety Information:
4-Chloro-2-bromo-benzoic acid is generally considered to have low toxicity under normal use and storage conditions. It may have an irritating effect on the eyes, skin, and respiratory tract.
