Abstract

In the proposed research paper a simple and accurate colorimetric method has been developed for the estimation of AZELNIDIPINE in bulk. The proposed method utilizes a smartphone camera and an application instead of the conventional UV spectrophotometer for the measurement of color intensity of a solution under consideration. This colorimetric method was found to be linear in the range of 2μg/ml to 10μg/ml concentration with an r2 value of 0.9993. The limit of detection (LOD) and the limit of quantification (LOQ) was found to be 0.024 μg/ml and 0.068 μg/ml respectively.

Keywords: AZL, Method development, Colorimetric method, LOD, LOQ.
