Online published on 24 December, 2019. Abstract First derivative spectrophotometric methods have been developed for the assay of Bumetanide using Shimadzu UV-1800 Model double beam UV-VIS spectrophotometer in reagents such as hydrochloric acid, phosphate buffer pH 3.6, phosphate buffer pH 2.0 and distilled water. Bumetanide has shown linearity 10–70 μg/ml in all the methods and the linear regression equations are found to be y = 0.0015x -0.0013 (R² = 0.9993), y= 0.0007x 0.0004 (R² = 0.9991), y = 0.0014x -0.0015 (R² = 0.9993) and y = 0.0014x -0.0015 (R² = 0.9995) in hydrochloric acid, phosphate buffer pH 3.6, phosphate buffer pH 2.0, and distilled water respectively. The methods are validated as per ICH guidelines and found to be precise, simple and accurate.
