butyryl chloride

butyryl chloride is a flammable liquid (flash point below 60 °C, Category 3). Store in a dedicated flammable storage cabinet, away from oxidisers and ignition sources. Use explosion-proof electrical equipment in storage areas. Containers must be kept tightly closed and grounded during transfer to prevent static discharge.

butyryl chloride is corrosive to skin, eyes, or metals. Store in acid-resistant or alkali-resistant cabinets as appropriate. Do not store in metal containers. Secondary containment (drip trays) is required. Segregate from incompatible substances such as strong oxidisers.

This substance carries the signal word DANGER, indicating the more severe hazard categories under GHS/CLP. Facilities handling butyryl chloride should ensure a written hazard communication programme, including current SDS, employee training records, and GHS-compliant labelling on all containers.
