Abstract
Vitamin K1 (phylloquinone) is essential for
blood clotting and bone health, and is present in numerous plants and dietary
supplements. In this study, the chemical structure of vitamin K1 was
investigated by FTIR spectroscopy to identify characteristic functional groups
and assess sample purity. The FTIR spectrum revealed specific bands
corresponding to quinone (C=O), alkyl (C–H), and aromatic (C=C) groups,
confirming the identity and structural integrity of vitamin K1. The results
demonstrate that FTIR is a rapid, non-destructive, and efficient method for the
qualitative characterization of vitamin K1, useful in the quality control of
pharmaceuticals and dietary supplements.
