Abstract:Two simple, rapid and inexpensive chemometric spectrophtometric methods were established for the stabilityindicating determination of aceclofenac in presence of its degradation product; diclofenac. The applied chemometric techniques are multivariate methods including partial least squares (PLS) and concentration residual augmented classical least squares (CRACLS).The UV absorption spectra of the standard solutions of the training and validation sets in phosphate buffer of pH 6 were recorded in the range of 220… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
