MESITYLENESULFONOHYDRAZIDE - Introduction

2,4, hydrazide is an organic compound. The following is a description of its nature, use, preparation and safety information:

Nature:
-Appearance: White crystalline solid.
-Molecular formula: C10H15N3O2S.
-Molecular weight: 253.31g/mol.
-Solubility: Good solubility in common organic solvents.

Use:
2,4, hydrazide is mainly used as an intermediate in organic synthesis. It can be used as a reducing agent, a hydrogenating agent, and a cyclization reagent during synthesis. It also has some applications in the field of pesticides and pharmaceuticals.

Method:
A common preparation method is to generate 2,4, 6-trimethylbenzenesulfonamide through the reaction of p-methyl magnesium bromide and 2,4-dimethyl nitropenn. The 2,4, 6-trimethylsulfonamide is then reduced to 2,4-sulfoxide by a reducing agent such as hydrazide.

Safety Information:
2,4, hydrazide has certain toxicity. Need to pay attention to protective measures when using. It can cause irritation, avoid contact with the eyes, skin and respiratory tract. Wear appropriate protective equipment, such as protective gloves, goggles and masks. Prolonged exposure and inhalation of dust should be avoided.

When operating, the laboratory safety regulations and correct operating instructions should be strictly observed. In case of any accident, appropriate first aid measures should be taken immediately and medical assistance should be sought.
