4-Chloro-3-cyanophenylboronic acid, 4-Chloro-3-cyanobenzeneboronic acid - Introduction
Acid is an organic compound with the chemical formula C7H5BClNO2. The following is a description of its nature, use, preparation and safety information:
Nature:
-Appearance: acid is white crystalline powder.
-Melting point: about 170-175°C.
-Solubility: Soluble in common organic solvents such as chloroform, disulfide and dimethyl sulfoxide, slightly soluble in water.
Use:
-acid is an important organic synthesis intermediate, commonly used in organic synthesis reactions. It can be used as a synthetic reagent for aromatic compounds and their derivatives.
Preparation Method:
-and acid is usually prepared by the following steps:
1. First, 4-chloro -3-cyanoiodobenzene is reacted with sodium hydroxide to generate the corresponding phenolate compound.
2. Then, the phenolate is reacted with boric acid and a catalyst to form a phenol acid.
Safety Information:
-the specific toxicity information of acid may be limited, so it should be handled with caution during use.
-Avoid skin contact and eye contact to avoid irritation. In case of contact, rinse immediately with plenty of water.
-Wear appropriate protective equipment such as lab gloves, goggles and lab coats during operation.
