It is applied as a synthetic building block and intermediate in organic synthesis particularly for protecting carbonyl groups in ketone reactions and preparing pharmaceuticals or complex molecules.

Its purpose is to protect ketones from nucleophilic attack during multi-step synthesis enabling selective functionalization of other parts of the molecule before deprotection.
