Acetamide

Acetamide (CH₃CONH₂) is a simple amide derived from acetic acid, appearing as a white, odorless, crystalline solid commonly used as a laboratory reagent, solvent, and plasticizer.​

Chemical Properties

Molecular formula: CH₃CONH₂ (C₂H₅NO)​

Molar mass: 59.07 g/mol​

Density: 1.159 g/cm³​

Melting Point: 79–81°C​

Boiling Point: 221.2°C​

Appearance: White crystalline solid; odorless or faint “mousy” odor​

Solubility: Highly soluble in water, ethanol, and many organic solvents​

Laboratory Uses

Acts as a solvent for organic and inorganic compounds due to high polarity and dielectric constant.​

Used as a plasticizer and softener in leather, textiles, paper, films, and explosives.​

Serves as a precursor for chemical synthesis (e.g., methylamine), in soldering flux, and as stabilizer for lacquers and explosives.​

Integral to biochemical and microbiological acetamide utilization tests for bacterial differentiation.​

Safety and Handling

Wear gloves, protective clothing, and eye protection; avoid skin and eye contact.​

Acetamide is suspected of being a carcinogen, so exposure should be minimized via good laboratory practices, ventilation, and hygiene.​

Avoid ingestion, inhalation of dust, and contact with strong acids or bases.​

Acetamide is valued as a versatile, polar solvent and chemical intermediate, but laboratory safety protocols must be followed strictly due to its potential health risks.
