Ethenzamide(CAS: 938-73-8)

Ethenzamide is a colorless or white crystalline solid with a molecular weight of approximately 132.13 g/mol. It has a melting point of 78-80°C and is slightly soluble in water but soluble in organic solvents like ethanol and acetone. Chemically, it is relatively stable but can react with strong bases. It is used in various applications due to its reactivity and solubility properties.

Ethenzamide is typically synthesized through the amidation of ethyl acetoacetate with ammonia or an amine under basic conditions. The reaction is usually catalyzed by sodium hydroxide. The process yields a mixture of products, but the desired ethenzamide can be isolated by recrystallization. The reaction is selective and the yield is generally good, around 70-85%.

Ethenzamide is used in the pharmaceutical industry for its potential as a drug intermediate. It is also employed in the polymer industry for its ability to act as a stabilizer and cross-linking agent. Additionally, it finds applications in the electronics industry as a component in sensors and semiconductors due to its chemical stability and reactivity.

When handling Ethenzamide, use appropriate personal protective equipment (PPE) such as gloves and safety goggles. Store it in a cool, dry place, away from strong acids, bases, and oxidizers. Use a fume hood during handling to avoid inhalation. In case of spill, contain the spill using an absorbent material and dispose of it according to local regulations. Always refer to the Safety Data Sheet (SDS) for detailed handling and safety information.
