AbstractA new simple, sensitive, and economic spectrophotometric method has been developed and validated for the determination of a new gabapentin derivative in pure form and pharmaceutical preparations. The method is based on the reaction between the amino group of gabapentin with benzene sulphonyl chloride to form the gabapentin derivative (sulphonamide) via addition-elimination mechanism. The new gabapentin derivative was prepared by two different methods using sodium carbonate (method 1) and sodium hydroxide (method 2). The colourless product obtained was analysed by TLC.
