Applications of 761-01-3
| Industry | Application | Process |
|---|---|---|
| Organic Synthesis | Used as a mild sulfonating agent for the preparation of sulfonic acids, sulfonyl chlorides, and sulfonamides | Reacted with alcohols, amines, or aromatic hydrocarbons in inert solvents (e.g., dichloromethane, chloroform) at low temperatures (0–25°C) to achieve selective sulfonation |
| Pharmaceutical Intermediate Synthesis | Employed to construct sulfonyl-containing drug molecules (e.g., sulfonamide motifs in protein kinase inhibitors and antithrombotic agents) | Reacted with nitrogen-containing heterocycles or aromatic amines under anhydrous conditions to form sulfonamide bonds; base (e.g., triethylamine) is typically added to neutralize the co-generated acid |
| Pesticide Development | Key sulfonating intermediate for synthesizing sulfonylurea herbicides (e.g., bensulfuron-methyl, pyrazosulfuron-ethyl) | Reacted with substituted anilines in aprotic solvents at 0–10°C; temperature control is critical to prevent over-sulfonation or decomposition |
| High-Performance Polymers | Used as an initiator or crosslinking aid for modifying ion-exchange membranes, including polysulfone and sulfonated polyether ether ketone (SPEEK) | Applied in post-polymerization sulfonation of pre-formed membranes via solid–liquid phase-transfer, enabling surface or bulk sulfonation to enhance proton conductivity |
