Description and Uses

4-(Benzyloxy)phenol, also called monobenzone and monobenzyl ether of hydroquinone (MBEH) is an organic chemical in the phenol family with chemical formula C6H5CH2OC6H4OH. It is used as a topical drug for medical depigmentation. Monobenzone occurs as a white, almost tasteless crystalline powder, soluble in alcohol and practically insoluble in water.
The topical application of monobenzone in animals, increases the excretion of melanin from the melanocytes. The same action is thought to be responsible for the depigmenting effect of the drug in humans.

Hydroquinone monobenzyl ether is an antidegradant added to rubber products; inhibitor in acrylic resins.
