General description

p-Toluidine is an aromatic amine. It can be detected in the water samples by homogeneous liquid-liquid extraction followed by ion mobility spectrometry (HLLE-IMS).[1]

Application

p-Toluidine may be used for the determination of hemoglobin adducts of aromatic amines in nonsmokers and smokers of blond- or black-tobacco cigarettes.[2] It may be used for the preparation of bidentate Schiff base ligand, via condensation with salicylaldehyde.
