2-Chloroaniline CAS 95-51-2

1. 2-Chloroaniline CAS 95-51-2 is primarily used as a key intermediate in the production of azo dyes and pigments for textiles and inks, notably as the dye base "Yellow GC" .
2. 2-Chloroaniline serves as a precursor in the synthesis of various pharmaceutical agents, agricultural chemicals (herbicides and pesticides), and polyurethane vulcanizing agents .
3. Applications of 2-Chloroaniline also include its use in polymer manufacturing and as a reagent in analytical chemistry .

1. Store 2-Chloroaniline CAS 95-51-2 in a tightly sealed container under inert gas (e.g., argon) in a cool, dry, well-ventilated place, protected from light and air, as it darkens upon exposure . Recommended storage temperatures vary from room temperature (in a cool, dark place <15°C) to refrigeration (2-8°C) .
2. Keep 2-Chloroaniline away from strong oxidizing agents, strong acids, and food and feedstuffs, as it is toxic and incompatible with these materials . Ground and bond container when transferring to avoid accumulation .
3. Always use appropriate personal protective equipment (PPE) including chemical-resistant gloves (butyl rubber recommended), tightly fitting safety goggles, face protection, and protective clothing; use only with adequate ventilation (fume hood) and avoid breathing vapors, mist, or dust .

1. Immediately isolate the spill area, eliminate all ignition sources, and use personal protection including self-contained breathing apparatus. Contain 2-Chloroaniline CAS 95-51-2 using inert, non-combustible absorbent material (e.g., dry sand) and do NOT let it enter drains or waterways .
2. Carefully collect leaking and 2-Chloroaniline in sealable containers as far as possible; absorb remaining liquid in sand or inert absorbent, and place all collected material into sealed, labeled chemical waste containers for proper disposal according to local, state, and federal environmental regulations .
3. Personnel must wear full chemical-protective equipment (chemical protection suit including SCBA) during cleanup; 2-Chloroaniline is classified for transport and is an aquatic toxin requiring hazardous waste disposal .

1. 2-Chloroaniline CAS 95-51-2 is classified as toxic in contact with skin (H311), harmful if swallowed or if inhaled (H302+H332), and causes serious eye irritation (H319) . 2-Chloroaniline CAS 95-51-2 is suspected of causing genetic defects (H341), damaging fertility or the unborn child (H361), and causing damage to organs through prolonged or repeated exposure (H372/H373) .
2. 2-Chloroaniline is combustible with a flash point of 104-108°C and auto-ignition temperature >500°C . It is very toxic to aquatic life with long-lasting effects (H400/H410), can be absorbed through the skin, and may cause methaemoglobinemia leading to cyanosis, dizziness, and confusion .
3. Always consult 2-Chloroaniline CAS 95-51-2 the specific Safety Data Sheet (SDS) for 2-Chloroaniline for complete hazard information, first-aid procedures, and handling instructions; precautionary statements include P260 (do not breathe vapors), P273 (avoid release to environment), P280 (wear protective gloves/eye protection), and P405 (store locked up) .
