Studies on the complexation between chloranilic acid and proguanil has been carried out. The chloranilic acid acted as a pi-electron donor. The stoichiometric relationship in the complex was determined by employing the Job’s method of continuous variation. The results indicate that the complex exhibits a purple colour and absorbs maximally at 520 nm. Spectrophotometric studies show that the method could be useful in the analysis of proguanil.
