444666-39-1 - Introduction
Acid is an organic compound with the chemical formula C6H4BClFO2. The following is a description of its nature, use, formulation and safety information:
Nature:
It is a solid with a white crystalline appearance. It is soluble in many organic solvents at room temperature, such as ether and dichloromethane. It can decompose at high temperatures and undergo intramolecular halogenation reactions.
Use:
It is an important intermediate in organic synthesis. It can be used to synthesize drugs, pesticides and other organic compounds. Its arylboronic acid derivatives can be used as crosslinkers and ligands for catalysts and solid phase reactions in organic synthesis.
Preparation Method:
Cr acid is usually prepared by the reaction of boric acid and 2-chloro-5-fluorophenylboronic acid. 2-Chloro-fluorophenylboronic acid and a base are first reacted to give the corresponding borate salt, which is then converted to fluorobacid by an acidification reaction.
Safety Information:
acrylic may be irritating to the skin and eyes. Wear appropriate protective equipment such as gloves and goggles during use or operation. Care should be taken to avoid direct contact with skin and eyes. It should be kept away from fire and oxidizing agents and stored in a dry, well-ventilated place. Prior to use or disposal, the relevant safety procedures should be understood in detail and observed.
