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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Aplicaciones
El 4,4′-dimetoxibenzhidrol se utilizó para estudiar la cinética y el mecanismo de oxidación de benzhidroles sustituidos a las benzofenonas correspondientes en presencia de Hg(OAc)2 por N-bromosuccinimida. Es útil en la protección de residuos de glutamina y asparagina en la síntesis de péptidos, reactivo para la N-protección de amidas.

Solubilidad
Soluble en agua (0,44 g/L a 25 °C) y metanol (0,1 g/ml).

Notas
Almacenar en condiciones frescas y secas, en un recipiente bien sellado. Almacénese lejos de los agentes oxidantes.
