Safety Data
General
Application
Used as a plasticizer and an industrial solvent.Acetamide has uses in electrochemistry and the organic synthesis of pharmaceuticals, pesticides, and antioxidants for plastics. It is a precursor to thioacetamide.
Acetamide has a high dielectric constant and is an excellent solvent for many organic and inorganic substances, and is widely used in various industries. It can be used as a solubilizer for some substances with low solubility in water, for example, as a solvent and solubilizer for dyestuffs in the fiber industry, and as a solvent in the synthesis of antimicrobial agents such as chloramphenicol. Acetamide is slightly alkaline and can be used as an antacid for varnish, explosives and cosmetics. Acetamide is hygroscopic and can be used as a wetting agent for dyeing; it can also be used as a plasticizer for plastics. Acetamide chlorination or bromination produces N-halogenated acetamide, which is a halogenated reagent for organic synthesis. Acetamide is also a raw material for the manufacture of drugs and fungicides. Acetamide is an antidote for the poisoning of fluoroacetamide, an organofluorine insecticide. The mechanism of action is that the chemical structure of the product is similar to that of fluoroacetamide, which can compete with acetamidase, so that fluoroacetamide does not produce fluoroacetic acid, eliminating the toxic effect of the latter on the tricarboxylic acid cycle and achieving the purpose of detoxification.
