O-Anisoyl Chloride CAS 21615-34-9

1. O-Anisoyl chloride is primarily used as an acylating agent in organic synthesis for introducing the o-methoxybenzoyl group into molecules.
2. O-Anisoyl chloride CAS 21615-34-9 serves as a key intermediate in the production of pharmaceuticals, agrochemicals, and dyes.
3. This compound is also utilized in polymer chemistry and materials science as a monomer or modifying agent.

1. Store o-anisoyl chloride in a cool, dry, well-ventilated place, away from heat, moisture, and incompatible materials (water, alcohols, bases, oxidizing agents). Use airtight containers under an inert atmosphere if possible.
2. Keep O-Anisoyl chloride CAS 21615-34-9 the container tightly sealed and clearly labeled. Handle and open containers only in a dry environment (e.g., glovebox or using dry techniques) to prevent violent hydrolysis.
3. Handle with extreme caution using appropriate personal protective equipment (PPE): chemical-resistant gloves, safety goggles, face shield, and an acid-resistant lab coat. Always use a fume hood.

1. Immediately evacuate and isolate the area. Ensure ventilation and wear full protective gear (gloves, goggles, protective clothing, respirator suitable for acid vapors).
2. **Do NOT use water.** Carefully O-Anisoyl chloride CAS 21615-34-9 cover or contain the spill with an inert, dry absorbent material (e.g., sand, vermiculite). Place all contaminated material in a sealed, labeled hazardous waste container.
3. Prevent the compound from entering drains, sewers, or the environment. Decontaminate tools and surfaces with a dry inert material first, then carefully clean with a non-aqueous solvent if necessary. Seek expert assistance.

1. O-Anisoyl chloride is **highly corrosive and moisture-sensitive**. It causes severe skin burns, eye damage, and respiratory damage. It is harmful if swallowed or inhaled. Reacts violently with water, alcohols, and bases, releasing heat and toxic/corrosive gases (hydrogen chloride, anisic acid derivatives).
2. O-Anisoyl chloride CAS 21615-34-9 is flammable and may emit toxic fumes (hydrogen chloride, carbon monoxide, phosgene) when heated to decomposition.
3. Always consult the official o-anisoyl chloride Safety Data Sheet (SDS) and handle it as a severe health, corrosion, and reactivity hazard. Specialized training and procedures for acid chlorides are required.
