O-Anisidine CAS 90-04-0

1. o-Anisidine CAS 90-04-0 is primarily used as a chemical intermediate in the synthesis of azo pigments and dyes .
2. The compound serves as a key building block for producing pharmaceuticals, agrochemicals, and specialty chemicals like the flavor agent vanillin .
3. o-Anisidine is also utilized in research for electrochemical studies and the investigation of conducting polymers .

1. Store o-Anisidine in a tightly sealed container under inert gas at refrigerated temperatures (0-10°C), as o-Anisidine is light, air, and heat sensitive .
2. Keep o-Anisidine CAS 90-04-0 strictly away from strong oxidizing agents, acids, acid chlorides, and acid anhydrides due to incompatibility .
3. Handle o-Anisidine using appropriate personal protective equipment including chemical-resistant gloves, safety goggles, and in a fume hood, as o-Anisidine is toxic and can be absorbed through the skin .

1. Isolate the spill area (at least 50 meters for liquids), eliminate all ignition sources, and wear full protective equipment including self-contained breathing apparatus before handling o-Anisidine .
2. Absorb liquid o-Anisidine CAS 90-04-0 using dry inert material like sand, collect using non-sparking tools into sealed, labeled containers for disposal, and prevent entry into drains or waterways .
3. Personnel cleaning o-Anisidine spills must decontaminate surfaces with 60-70% ethanol followed by soap and water, and dispose of waste through a licensed hazardous waste facility .

1. o-Anisidine is classified with GHS signal word "Danger" and is toxic if swallowed, in contact with skin, or if inhaled (H301+H311+H331) .
2. o-Anisidine is suspected of causing cancer (H351) and genetic defects (H341), and may cause damage to organs through prolonged or repeated exposure (H373) .
3. o-Anisidine CAS 90-04-0 has a flash point of 100-111°C, is combustible, and thermal decomposition produces toxic fumes including carbon oxides and nitrogen oxides; o-Anisidine is classified for transport as a poison (UN2431, Hazard Class 6.1, PG III) .
