1-Bromo-3,3,3-trifluoroacetone is used in the preparation of 3-nonylthio-1,1,1-trifluoropropan-2-one and perfluoroalkylated trans-allylic alcohols. It is involved in the synthesis of cyclic tetrapeptides. Further, it reacts with potassium enolate of ethyl 4,4,4-trifluoroacetoacetate to produce ethyl 2,4-bis(trifluoromethyl)-4-hydroxydihydro-3-furoate.
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.
