Benzenesulfonylchloride,2-nitro- - Introduction
2-nitrobenzenesulfonyl chloride (2-nitrobenzenesulfonyl chloride) is an organic compound with the chemical formula C6H4ClNO3S. The following is an introduction to its nature, use, preparation and safety information:
1. Nature:
2-nitrobenzensulfonyl chloride is a yellow crystalline solid with a pungent odor. It is poorly soluble in water, but easily soluble in organic solvents. Under high temperature, light and humidity conditions, 2-nitrobenzensulfonyl chloride may decompose.
2. Use:
2-nitrobenzenesulfonyl chloride is often used as an important reagent in organic synthesis. It can be used to synthesize other organic compounds, such as O-nitrobenzenesulfonamide and so on. In addition, it can also be used as an intermediate for dyes, pigments and pesticides.
3. Preparation method:
The preparation of 2-nitrobenzenesulfonyl chloride is usually obtained by reacting p-nitrobenzene sulfonic acid with liquid thionyl chloride. The reaction is carried out at a low temperature, and the reaction product is usually isolated by crystallization.
4. Safety Information:
2-nitrobenzensulfonyl chloride is irritating and should be kept away from eye and skin contact. Pay attention to personal protective measures during operation, such as wearing chemical protective gloves and goggles. Avoid contact with oxidants and flammable materials during storage and handling to prevent the risk of fire and explosion. During use or disposal, please follow the relevant regulations and safety operation guidelines.
