2-甲苯甲烷磺酰氯 - Introduction

(2-Methylphenyl)methanesulfonyl chloride (abbreviated as MTMSC) is an organic compound with the chemical formula C8H9ClO2S. It is a colorless to pale yellow liquid with a strong pungent odor at room temperature. It has a density of 1.33g/cm³ and a boiling point of 198-200°C. MTMSC is a compound sensitive to air and water, so it needs to be stored and handled with care to prevent moisture and dust.

MTMSC is widely used in the field of organic synthesis, mainly as a functional group protective agent. It can be used as a chlorinating agent to replace basic functional groups (such as alcohols, amines, etc.) in other compounds with corresponding sulfonyl chloride functional groups for subsequent synthesis reactions. MTMSC can also be used as intermediates for the preparation of other organic compounds, such as drugs, dyes and various organic synthesis reactions.

(2-Methylphenyl) The preparation method of methanesulfonyl chloride is usually to react 2-methylbenzenesulfonic acid (2-Methylbenzenesulfonic acid) with a preparation chlorinating agent (such as phosphorus oxychloride) to obtain the target product MTMSC. The specific reaction conditions can be optimized according to the actual situation.

When handling MTMSC, safe practices must be followed, including wearing appropriate protective equipment (such as gloves, goggles, and protective clothing) and equipment for ventilation. Due to its irritation and sensitivity to water, direct contact with the skin or inhalation of its vapors should be avoided. During storage, MTMSC should be kept in a closed container, away from fire and oxygen. Environmental protection regulations shall be strictly observed when handling and disposing of wastes.
