4-Benzylamino-1-butanol is primarily utilized in organic synthesis as an intermediate for the preparation of various pharmaceutical compounds. Its structure, featuring both an amino and a hydroxyl group, makes it a versatile building block in the development of drugs, particularly those targeting neurological and cardiovascular systems. Additionally, it is employed in the synthesis of surfactants and emulsifiers due to its amphiphilic nature, which allows it to interact with both water and oil phases. This compound also finds application in the production of specialty chemicals used in agrochemicals and personal care products, where its functional groups contribute to the desired chemical properties.
