Lanthanum trifluoromethanesulfonate, anhydrous, 99%


Chemical Properties

Formula Weight
Soluble in water.


Lanthanum trifluoromethanesulfonate is used in the Aldol reaction of silyl enol ethers with aldehydes. It is an effective catalyst for the Baylis-Hillman reaction. It also catalyzes Michael additions to methyl vinyl ketone in water.


Keep the container tightly sealed. Store in a cool, dry conditions in well sealed containers. Incompatible with bases. It is hygroscopic in nature. Store under dry inert gas.
