Aplicaciones

1,3-Dichloroacetone is used in the synthesis of citric acid. It is used as a solvent and as an intermediate in organic synthesis. Further, it serves as an acceptor substrate in the cross-aldol reaction with donor substrates such as acetone, cyclopentanone and cyclohexanone. It is also used in the preparation of an active pharmaceutical ingredient, famotidine.

Notas

Hygroscopic. Store in a cool place. Incompatible with strong oxidizing agents, strong bases and reducing agents.
