Benzhydrylideneaminooxy-phenyl-acetic acid, also known as diphenhydramine, is a chemical compound with the molecular formula C17H21NO. It is an ethanolamine derivative and a first-generation antihistamine, primarily used to treat symptoms of allergies, such as sneezing, itching, and runny nose.

It is commonly found in over-the-counter medications like Benadryl and is also used as a sleep aid due to its sedative effects.
