21971-21-1 - Introduction
acid (acid) is an organic compound, commonly abbreviated as CMBA in chemistry. Its chemical formula is C8H7ClO3.
Nature:
A white or light yellow crystalline solid with low solubility. It is stable at room temperature and not volatile. It has a molecular weight of 182.6g/mol.
Use:
acid is an important organic synthesis intermediate, commonly used in drug synthesis and preparation of dye intermediates. It can also be used as a synthetic raw material for pesticides.
Method:
It can be obtained by the refining reaction of phenol. The specific preparation method is generally the reaction of 2-methoxyphenol with thionyl chloride under alkaline conditions, and then treated to obtain the desired product.
Safety Information:
The acid is irritating to the human body, and care should be taken to avoid contact with skin, eyes and inhalation. Wear protective gloves, goggles and respiratory protective equipment during use or handling. In case of contact with skin or eyes, rinse immediately with plenty of water and seek medical help. At the same time, acid should be stored in a dry, ventilated place, away from fire and flammable materials.
