Spectrophotometric Methods for Ambroxol by Mima Azrah is a document available to read on EtoBox.

This document describes three simple spectrophotometric methods for the determination of ambroxol hydrochloride, a mucolytic agent, from pharmaceutical formulations. The methods involve diazotizing ambroxol hydrochloride with sodium nitrite and acetic acid, then coupling the product with catechol, resorcinol or β-naphthol in an alkaline medium to form colored species. The absorbance of these species is measured at 425 nm. The methods show good linearity, precision and accuracy for quantifying ambroxol hydro
