25300-37-2 - Introduction

chloride is an organic compound with the chemical formula C7H6ClClO2S, commonly abbreviated as CMBS. It is a white solid crystal, insoluble in water at room temperature.

The compounds are commonly used as reagents and intermediates in organic synthesis reactions. It has an electrophilic sulfonyl chloride functional group that can undergo substitution reactions with nucleophiles and is commonly used in the synthesis of target molecules with a benzenesulfonyl group. It is also widely used in medicine for the synthesis of bioactive molecules and drugs.

The preparation method of chloride is usually obtained by reacting p-methylbenzenesulfonyl chloride with thionyl chloride. The reaction is usually carried out at room temperature and the 6-methyl position is selectively substituted.

When using chloride, be aware of its toxicity and irritation. It is a corrosive compound that can cause severe chemical burns on contact with the skin and eyes. Wear appropriate protective gloves, glasses and protective clothing during operation. In addition, it should also be away from fire and oxidizing agents, avoid contact with flammable substances. When stored, it should be kept in a sealed, dry and cool place.
