4,4?-Dimethoxybenzhydrol was used to study the kinetics and mechanism of oxidation of substituted benzhydrols to corresponding benzophenones in the presence of Hg(OAc)2 by N-bromosuccinimide. It is useful in the protection of glutamine and asparagine residues in peptide synthesis, reagent for the N-protection of amides.

Reagent for the N-protection of amides, useful in the protection of glutamine and asparagine residues in peptide synthesis. Substitution of the OH group with amide and a variety of other N functionalities occurs readily in AcOH with H2SO4 catalysis: Chem. Ber., 103, 2041 (1970); Synthesis, 495 (1996). Deprotection occurs in TFA.
