Green stability-indicating RP-HPTLC technique for determining croconazole hydrochloride

Abstract

The objective of the proposed investigation is the development and validation of a green stability-indicating reverse-phase high-performance thin-layer chromatographic method to determine croconazole hydrochloride (CCZ). The developing system used was an 80:20 v/v mixture of acetone and water. The measurement of CCZ was done at 198 nm. With the use of the Analytical Eco-Scale (AES), ChlorTox, and Analytical GREEnness (AGREE) tools, greenness was evaluated. The linearity was demonstrated by the present method in the 25-1,200 ng/band range. The present approach was additionally reliable, accurate, sensitive, precise, and green. An exceptional greenness profile was demonstrated by the AES, total ChlorTox, and AGREE scales, which were determined to be 89, 1.08 g, and 0.82, respectively. The greenness metrics of the present method were much better than the reported high-performance liquid chromatography approach. Under acid and oxidative degradation circumstances, CCZ was shown to be unstable, while under alkaline and thermal-stress settings, it was sufficiently stable. Furthermore, the stability-indicating component determined by analytical method identified CCZ in the presence of its degradation products. Commercial CCZ cream was found to contain 0.98% w/w of CCZ. The investigation's results suggested that CCZ in commercially available creams might be regularly examined with the help of the recommended green technology.
