2-Chlorobenzotrichloride CAS 2136-89-2

1. 2-Chlorobenzotrichloride is primarily used as in the production of 2-chlorobenzoyl chloride .
2. 2-Chlorobenzotrichloride CAS 2136-89-2 serves as an organic synthesis raw material for manufacturing dyes and other pharmaceutical intermediates .
3. 2-Chlorobenzotrichloride is produced via the chlorination of 2-chlorotoluene or toluene, and is also identified as an impurity standard for pharmaceutical quality control .

1. Store 2-Chlorobenzotrichloride in a tightly sealed container under inert gas (e.g., nitrogen) in a cool, dry, well-ventilated place, as it is moisture sensitive and can decompose upon contact with water .
2. Keep 2-Chlorobenzotrichloride CAS 2136-89-2 away from strong oxidizing agents and sources of ignition; recommended storage temperatures range from room temperature (in a cool, dark place) to refrigeration (below 15°C) .
3. Handle 2-Chlorobenzotrichloride using appropriate personal protective equipment including chemical-resistant gloves and safety goggles, and work in a fume hood to avoid breathing dust or vapors .

1. Isolate the spill area, ensure adequate ventilation, and avoid generating dust; wear full protective equipment including self-contained breathing apparatus before handling 2-Chlorobenzotrichloride .
2. Sweep up solid 2-Chlorobenzotrichloride CAS 2136-89-2 into sealed, labeled containers for disposal without creating dust; prevent entry into drains or waterways .
3. Personnel cleaning 2-Chlorobenzotrichloride spills must dispose of waste according to hazardous material regulations, as 2-Chlorobenzotrichloride is classified for transport as a corrosive substance (UN 3261 or UN 1759, Hazard Class 8, Packing Group II/III) .

1. 2-Chlorobenzotrichloride is classified with GHS signal word "Danger" according to TCI, causing severe skin burns and serious eye damage (H314) and is harmful if swallowed (H302) . Other sources classify it as a carcinogen category 1B (H350, may cause cancer) and require special handling instructions before use (P201, P202) .
2. 2-Chlorobenzotrichloride CAS 2136-89-2 is an acute toxic category 4 oral substance that causes skin and serious eye irritation (H315, H319), may cause respiratory irritation (H335), and has an NFPA health rating of 3 (serious hazard) .
3. 2-Chlorobenzotrichloride has a melting point of 29-31°C, flash point of 98°C (209°F), and is very toxic to aquatic life with long-lasting effects (H400, H413), requiring prevention of environmental release .
