Description

Triethyl orthoacetate is the ethyl orthoester of acetic acid. It is an oily liquid with a pungent odor. Triethyl orthoacetate is used as a water scavenger and as intermediate for synthesis of pharmaceuticals. It is used in organic synthesis for the introduction of the acetate group to an alcohol and in the Johnson-Claisen rearrangement.
