What is Benzylamine?

Benzylamine is a primary amine compound having benzyl as the N-substituent. It has been isolated from Moringa oleifera (horseradish tree). It has a role as an allergen, a plant metabolite and an EC 3.5.5.1 (nitrilase) inhibitor. It is an aralkylamine and a primary amine. It is a conjugate base of a benzylaminium.
