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

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 UVvisible 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.
