Its local anaesthetic properties have been used for surface anaesthesia of the skin and mucous membranes, and for relief of pain and itching associated with some anorectal disorders. It has a role as a local anaesthetic. It is a benzoate ester, a substituted aniline, an amino acid ester and a primary amino compound. It is functionally related to a 4-aminobenzoic acid and a butan-1-ol. It is a conjugate base of a butamben(1+)."}]
