ethyl O-methylsulphonylacetohydroxamate - Introduction

Ethyl O-methylsulphonylacetohydroxamate is a compound commonly abbreviated as EMSA. It has a chemical formula of C8H13NO5S and a molecular weight of 239.26g/mol.

EMSA is a colorless crystalline powder with a pungent odor. It is insoluble in water and soluble in organic solvents. EMSA is highly stable, but may decompose when heated.

EMSA is mainly used in organic synthesis of color reagents and reagents. It can be used as a detection reagent for iron ions and can form stable color complexes. In addition, it can also be used to inhibit metal corrosion and to study enzymatic reactions in organisms.

The method of preparing EMSA is to react acetyl hydroxamic acid with p-toluenesulfonyl chloride to form the corresponding sulfonyl chloride derivative. It is then reacted with ethanol to form the final ethyl acetohydroxamate product.

Regarding the safety information of EMSA, it is necessary to pay attention to its pungent odor and maintain good ventilation during operation. It is an irritant compound that may cause irritation when in contact with the skin and eyes, and may have effects on the central nervous system. Wear appropriate personal protective equipment and follow all safe operating procedures.
