FTIR, FT Raman and UV-Visible Spectroscopic Analysis on Metformin Hydrochloride

Abstract

Metformin hydrochloride is an antidiabetic drug. The FTIR and FT Raman spectra of the compound has been recorded and a qualitative analysis on the vibrational bands has been carried out. The light absorption activity in the UV-vis region of the drug under different storage conditions has also been analyzed. Further, the absorption ratio referred to as Q value used in confirmatory test of identity is evaluated from the UV-visible spectra of the compound. The characteristic vibrational frequencies of the drug have been identified and assigned using FTIR spectrum, is also confirmed using FT Raman spectrum. A comparison after the sample stored in the ideal conditions and are exposed to environmental hazards is made.
