CAS 431-67-4: 1,1-dibromo-3,3,3-trifluoroacetone

3,3-Dibromo-1,1,1-trifluoroacetone

1,1-Dibromo-3,3,3-trifluoroacetone readily forms trifluoropyruvaldehyde hydrate in the presence of aqueous NaOAc, which is a useful intermediate, e.g. in the synthesis of a fused pyrazine derivative. This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

1,1-Dibromo-3,3,3-trifluoroacetone is an analog of the promiscuous substrate 1,1-dibromoethane. It undergoes basic hydrolysis and has been shown to be a horticultural and pharmacological agent. The trifluoromethyl group makes this molecule reactive and provides an ultrafast reaction with nucleophiles. This reactivity makes it difficult to determine which functional groups are present in the molecule. However, by using a control experiment, it was determined that the imino and imidazole groups are present in the molecule.
