High Performance Liquid Chromatography (HPLC) Method for Analysis of Doxazosin mesylate
Doxazosin is a quinazoline derivative with the molecular formula of C23H25N5O5 • CH3SO3H . It is primarily used as a prescription medication for treatment of hypertension and its symptoms. It is an alpha-blocker that relaxes blood vessels and muscles.
Doxazosin mesylate can be retained and analyzed using the Newcrom R1 stationary phase column. The analysis utilizes an isocratic method with a simple mobile phase consisting of water and acetonitrile (MeCN) with a triethanolamine buffer. Detection is performed using UV.
