Article	Year
A spectrophotometric method for the determination of metoclopramide HCl and dapsone. Journal of pharmaceutical and biomedical analysis, 2001, Volume: 25, Issue:3-4 A rapid, sensitive and selective spectrophotometric method has been developed for the quantitative determination of metoclopramide hydrochloride (MCP) and dapsone (DAP) in both pure and dosage forms. The method is based on the diazo coupling reaction of the drugs with a new coupling agent, dibenzoyl methane in an alkaline medium. The resulting coloured azo dyes exhibit maximum absorption at 440 nm for MCP and at 470 nm for DAP with a molar absorptivity of 2.85x10(4) and 1.71x10(4) l mol(-1) cm(-1) for MCP and DAP, respectively. All variables have been optimized. No interferences were observed from excipients and the validity of the method was tested against reference method.
