    Abstract: A rapid and validated spectrophotometric method has been developed for determination of Diazepam (DZP) in pure and pharmaceutical dosage forms. The method was based on ion-pair association reaction of DZP with ferrithiocyanide complex in acidic medium. The color development was monitored spectrophometrically at the maximum absorption, λmax = 506 nm... Show More
