C2H52NH

C2H52NH, commonly written (C2H5)2NH, refers to diethylamine, a secondary amine with the molecular formula C4H11N. It is a colorless liquid at room temperature with a characteristic strong, ammonia-like odor and is miscible with water and many organic solvents.

Diethylamine acts as a weak base and readily forms salts with acids. It is flammable and should be handled in a well-ventilated area, away from oxidizers and sources of ignition. It can react with air to form peroxides upon prolonged exposure, so storage under appropriate conditions, typically in tightly closed containers and with attention to peroxide precautions, is recommended.

Uses of diethylamine are varied and industrially important. It serves as a versatile intermediate in organic synthesis, including the preparation of other amines, pharmaceuticals, dyes, pesticides, and surfactants. It is also used to manufacture diethylaminoethyl (DEAE) reagents for cellulose derivatives and chromatography, and it functions as a base in a wide range of reactions.

Safety and handling considerations are important due to its irritant properties. Exposure can irritate skin, eyes, and the respiratory tract. Adequate ventilation, protective equipment, and appropriate storage and handling practices are advised to minimize health risks. It should be kept away from incompatible materials such as strong oxidizers and strong acids, and used with standard laboratory or industrial chemical safety procedures.
