O-Toluic Acid CAS 118-90-1

1. O-Toluic acid is primarily used as a key intermediate in organic synthesis for producing pharmaceuticals, agrochemicals (e.g., the fungicide phosphamide), dyes, and plasticizers .
2. The compound serves as a raw material in the manufacture of specialty chemicals such as spices, film color developers, and polymerization initiators like MBPO . O-Toluic acid CAS 118-90-1 also plays a role as a xenobiotic metabolite in biochemical research .
3. Applications of O-Toluic acid also include its use in polymer production to enhance material properties and as a standard in analytical chemistry techniques .

1. Store O-Toluic acid in a tightly sealed container in a cool, dry, and well-ventilated area away from heat, sparks, and open flames . Recommended storage is at room temperature (RT) or for long-term stability, at -20°C .
2. Keep O-Toluic acid CAS 118-90-1 strictly away from strong oxidizing agents and strong bases, as it is incompatible and combustible .
3. Always use appropriate personal protective equipment (PPE) including chemical-resistant gloves, safety goggles, and protective clothing when handling O-Toluic acid; avoid dust generation and use with adequate ventilation .

1. Immediately isolate the spill area and eliminate all ignition sources; contain O-Toluic acid using inert, non-combustible absorbent material (e.g., dry sand) and avoid generating dust .
2. Carefully sweep up or shovel O-Toluic acid CAS 118-90-1 into a sealed, labeled chemical waste container for proper disposal according to local, state, and federal environmental regulations .
3. Personnel must wear suitable PPE including self-contained breathing apparatus (SCBA) during cleanup; prevent material from entering drains or waterways as it is an environmental hazard .

1. O-Toluic acid is classified as a combustible substance (flash point 148°C) and causes skin irritation (H315), serious eye irritation (H319), and may cause respiratory irritation (H335) . Acute toxicity includes oral LD50 of 400 mg/kg in rats .
2. O-Toluic acid is harmful if swallowed, inhaled, or absorbed through the skin; thermal decomposition or combustion produces toxic and irritating fumes including carbon monoxide and carbon dioxide .
3. Always consult O-Toluic acid CAS 118-90-1 the specific Safety Data Sheet (SDS) for O-Toluic acid for complete hazard information, first-aid procedures (P305+P351+P338 for eyes, P301+P330+P331 for ingestion, P302+P352 for skin), and handling instructions .
