The application of VIS spectrophotometric determination of enalapril maleate in substance, in tablets and estimation of ester group stability.
A new spectrophotometric VIS method is proposed for the determination of enalapril maleate in pure substance and in tablets. Attempts have been made to estimate stability of the ester group in the molecule of enalapril maleate in the solid phase at 70 degrees C.
