The color of a pharmaceutical product has implications towards a variety of different aspects in the drug product development process. Both the US and European Pharmacopoeia describe analysis methods needed to quantitatively determine the color of a drug product, including acquiring CIE Lab color values.
The application of UV-Visible spectroscopy can provide absorption spectra of either liquids or powders. For pharmaceutical quality control via color analysis, these spectra are collected and used to determine the color values of the pharmaceutical products.
