  • Title: Spectrophotometric analysis of raloxifene hydrochloride in pure and pharmaceutical formulations.
    Author: Dharuman J, Ravichandran V, Thirumoorthy N, Dharamsi A.
    Journal: Pharmazie; 2004 Sep; 59(9):720-1. PubMed ID: 15497756.
    Abstract:
    Two simple and sensitive spectrophotometric methods (A and B) for the determination of raloxifene hydrochloride in bulk samples and pharmaceutical formulations are described. Method A is based on the oxidation of the drug with ferric chloride and coupling with potassium ferric cyanide. Method B is based on reduction of the drug with Fehling's reagent. Bluish green color formed in method A absorbs at 735 nm and brown color produced in method B absorbs at 430 nm.
