Overview
3,4-Dichlorophenyl isocyanate (CAS: 2795-18-0) is a specialized aromatic isocyanate with the molecular formula C7H3Cl2NCO. It is primarily produced via phosgenation of 3,4-dichloroaniline and serves as a critical intermediate in synthesizing high-performance polyurethanes.
Application
- Polyurethane foam manufacturing for industrial insulation.
- Synthesis of chlorinated herbicides and agrochemicals.
- Production of specialty coatings and adhesives requiring chemical resistance.
Precautions
Strict storage below 25°C in dry, ventilated areas away from moisture is mandatory. Personnel must utilize full PPE including respiratory protection due to severe respiratory sensitization risks. Not intended for clinical use; handle only in controlled industrial environments.
