Abstract

Visible Spectrophotometric Method For The Determination Of Salmeterol Xinafoate

Author(s): K. P. R Chowdary, G Devala Rao

A simple and sensitive visible spectrophotometric method based on the reaction of salmeterol xinafoate with diazotised dapsone under alkaline conditions to form a stable orange colored chromogen, which can be quantitatively measured at 465 nm, is reported.
