Application:	Sodium acetate can be used as a base to synthesize:• Oxazolones via Erlenmeyer Plochl condensation reaction of aromatic aldehydes and hippuric acid. • Cinnamic acids via Perkin reaction between aromatic aldehydes and acid anhydrides. A mixture of sodium acetate-acetic acid buffer can be employed in the polybromination of substituted imidazoles to synthesize polybrominated imidazoles. It can also be used as a catalyst in tandem Knoevenagel-Michael multicomponent reactions.
General description:	Sodium acetate is a hydrophilic organic compound that can be prepared by treating acetic acid with sodium carbonate or sodium hydroxide. It acts as neutralizing agent, catalyst, food additive, and buffer to maintain a specific pH.
