용도

1,1,1-Trifluoroacetone is used in a synthesis of 2-trifluoromethyl-7-azaindoles starting with 2,6-dihalopyridines. The derived chiral imine was used to prepare enantiopure α-trifluoromethyl alanines and diamines via a Strecker reaction followed by either nitrile hydrolysis or reduction. And also used as a useful molecule in synthesis reactions.

참고

Air Sensitive. Store in cool, dry conditions in well sealed containers. Keep container tightly closed.
