Spectroscopy is an analytical technique used to measure and identify chemical compounds through their interaction with electromagnetic radiation. Spectroscopy has become a common method for the characterization and identification of different compounds. As a result, techniques such as UV-Vis, infrared (IR), nuclear magnetic resonance (NMR), and mass spectrometry (MS) have become invaluable tools in the elucidation of the structure of chemical compounds, as well as their determination. Use of spectroscopy In the case of Daclatasvir hydrochloride, spectroscopy can be used to directly identify and quantify the compound’s active ingredient. Daclatasvir hydrochloride (DCV-HCl) is an antiviral medication that is used to treat a variety of diseases and infections, such as chronic hepatitis C virus (HCV) infections. Use of UV visible spectroscopy UV-Vis spectroscopy is the most commonly used technique to detect and identify DCV-HCl, due to its sensitivity and selectivity. UV-Vis spectroscopy i...
