Study of Characterization of Commercial Drugs Using FTIR, XRD and TGA Technique

Minerals are minute amounts of metallic elements that are vital for the healthy growth of teeth and bones. The activity of drug is intimately related to its chemical structure. Knowledge about the chemical structure a drug is useful for Synthesis of new compounds with more specific actions and in understanding the mechanism of drug action. Hence an attempt has been made to study the physico-Chemical characteristic of commercial drugs in solid state using FT-IR, Thermal and X-ray diffraction measurement. Some specific modes of vibrations are identified and the absorbance values are noted. The intensity ratio of Phosphate to Silicate I 1028/I756 were found to 0.66 for drug A, 0.33 for drug B and 0.83 for drug C. The presence of certain minerals such as Phosphate, Silicate, and Sulphate were identified.
