Overview
3-Pyridinesulfonyl Chloride (CAS: 2608-57-9, Formula: C6H4NClO2S) is a key heterocyclic intermediate synthesized via chlorination of nicotinic acid. It serves as an essential electrophilic reagent for constructing sulfonyl-pyridine scaffolds.
Application
- Pharmaceutical synthesis: Precursor for anti-inflammatory and antiviral agents.
- Agricultural chemistry: Building block for pyridyl-based herbicides.
- Material science: Used in developing specialized functional polymers.
Precautions
Store under inert atmosphere at 2-8°C. Strictly avoid moisture due to hydrolysis risks. Personnel must use full PPE; exposure causes severe skin burns and respiratory irritation.
