Description

Application

• Boron trichloride, a Lewis acid, is a general reagent for the cleavage of a wide range of ether and acetal protecting groups.
• It is a useful reagent to directly convert aromatic aldehydes to the corresponding gem-dichlorides.
• It can also be used in the transmetallation reaction with less nucleophilic reagents such as tin and zirconium organometallic compounds to synthesize a variety of organoboranes.

For preparing methyl esters of fatty acids and for transesterification of triglycerides.

Packaging
