4-Ethoxybenzoyl Chloride CAS 16331-46-7

1. 4-Ethoxybenzoyl chloride is primarily used as an acylating agent in organic synthesis for introducing the 4-ethoxybenzoyl group into molecules, particularly in the production of pharmaceuticals and agrochemicals.
2. 4-Ethoxybenzoyl chloride CAS 16331-46-7 serves as a key intermediate in the synthesis of dyes, fragrances, and liquid crystal materials.
3. This compound is also utilized in polymer chemistry and materials science as a monomer or modifying agent.

1. Store 4-ethoxybenzoyl 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 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 4-Ethoxybenzoyl chloride CAS 16331-46-7 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 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 4-Ethoxybenzoyl chloride CAS 16331-46-7 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. 4-Ethoxybenzoyl 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, 4-ethoxybenzoic acid derivatives).
2. 4-Ethoxybenzoyl chloride CAS 16331-46-7 is flammable and may emit toxic fumes (hydrogen chloride, carbon monoxide, phosgene) when heated to decomposition.
3. Always consult the official 4-ethoxybenzoyl 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.
