3-Nitrobenzensulfonyl chloride - Introduction
m-Nitrobenzenesulfonyl chloride is an organic compound whose chemical formula is C6H4ClNO4S. The following is an introduction to the properties, uses, preparation methods and safety information of m-nitrobenzene sulfonyl chloride:
Nature:
m-Nitrobenzenesulfonyl chloride is a yellow crystal with a pungent odor. It is stable at room temperature, but a decomposition reaction occurs when heated. This compound is flammable and insoluble in water, but can be dissolved in organic solvents.
Use:
m-Nitrobenzenesulfonyl chloride is an important intermediate in organic synthesis. It is commonly used in the synthesis of organic compounds such as pharmaceuticals, dyes and pesticides. In addition, it can also be used as a chlorination reagent, a reagent for the removal of thiols, and an important reagent in chemical analysis.
Method:
m-Nitrobenzenesulfonyl chloride can be prepared by the iodination reaction of p-nitrobenzenesulfonyl chloride. The specific step is to dissolve nitrophenylthionyl chloride in chloroform, then add sodium iodide and a small amount of hydrogen iodide, and heat the reaction for a period of time to obtain m-nitrobenzenesulfonyl chloride.
Safety Information:
m-Nitrobenzenesulfonyl chloride is a toxic substance that is irritating to the skin, eyes and respiratory tract. When operating, avoid contact with skin and eyes, and ensure that the operation is carried out in a well-ventilated place. Personal protective equipment such as protective gloves, safety glasses and protective masks should be worn when using the substance. In addition, m-nitrobenzene sulfonyl chloride should be properly stored, away from fire sources and oxidants, and avoid contact with combustibles. In the event of mishandling or accident, seek medical attention immediately and take the compound's safety data form to the hospital.
