Benzenesulfonamide, 3-cyano- (9CI) - Introduction
3-cyanobenzensulfonamide is an organic compound with the chemical formula C8H6N2O2S. The following is a description of its nature, use, preparation and safety information:
Nature:
-3-cyanobenzensulfonamide is a solid, usually white crystalline.
-Its molecular weight is about 200.2g/mol.
-It is slightly soluble in water and has good solubility in organic solvents such as ethers and alcohols.
Use:
- 3-Cyanobenzenesulfonamide can be used as an intermediate in organic synthesis.
-It is often used in drug synthesis to construct the molecular skeleton, as a starting point for the synthesis of amino acid derivatives, or as a precursor for the preparation of other organic compounds.
-In addition, it can also be used in chemical analysis, biochemical research and pharmaceutical fields.
Method:
-The preparation of 3-Cyanobenzenesulfonamide is usually obtained by the reaction of benzonitrile and benzenesulfonyl chloride.
-The reaction is usually carried out at room temperature, and the hydrogen chloride produced is neutralized by adding an alkaline medium (such as sodium carbonate).
-The resulting 3-cyanobenzensulfonamide can be crystallized from the reaction solution.
Safety Information:
-3-cyanobenzensulfonamide is generally relatively safe under normal conditions of use.
-Because it is a chemical, appropriate laboratory safety practices should be used, such as wearing protective gloves, eye protection, and protective clothing.
-Avoid contact with skin and inhalation of gas or dust during use.
-It should be stored in a cool, dry and airtight container, away from fire and oxidizing agents.
Please note that the above is only a general description of 3-cyanobenzensulfonamide, and it needs to be evaluated and operated according to specific conditions in actual applications.
