Storage method

This product should be sealed and stored in a cool, dry place.

Synthesis method

1. The methylsulfonyl chloride obtained by reacting dimethyl sulfate with sodium thiosulfate is esterified with ethanol to obtain ethyl methanesulfonate.

2. Preparation method:

Mix methanesulfonyl chloride (2) and absolute ethanol evenly, cool to 0°C, slowly add pyridine dropwise while stirring, and control the temperature of the reaction solution Not exceeding 10℃. After addition, acidify with hydrochloric acid and extract twice with diethyl ether. The ether layer was washed with water, washed with 5% sodium carbonate solution to pH 7-8, and dried over anhydrous sodium sulfate. After distilling off the ether, distill under reduced pressure and collect the fraction at 85-86°C/1.33kPa to obtain compound (1). ^[1]

Purpose

Used as a bacterial mutagen, as well as in organic synthesis and cancer research.
