Abstract N ‐Hydroxy‐ N ‐ p ‐chlorophenyl‐N′‐(2‐methyl‐5‐chloro)‐phenyl‐ p ‐toluamidine hydrochloride (HCPMCPTH) reacts with vanadium(V) to form a 1:2 (metal:reagent) blue‐violet complex which can be quantitatively extracted into chloroform from acetic acid solutions. The deep blue adduct having 1:2:1 (V:HCPMCPTH:PCP) stoichiometry gets quantitatively extracted into chloroform from 0–2.5 M acetic acid media. The formation of the ternary complex has been made the basis for the development of a simple, rapid, sensitive and selective extractive‐photometric method for the determination of microamounts of vanadium(V). The method has been applied to the determination of vanadium in steels.
