The United States Pharmacopeia (USP) sets standards for the quality, purity, and strength of medicines and food ingredients. USP standard norms for UV/Vis spectroscopy involve the use of spectrophotometers to measure the absorbance of light at different wavelengths.

These standards help ensure that medicines and other substances are properly identified and have the expected quality attributes. The USP has published general chapters and monographs related to UV/Vis spectroscopy, which describe approved methods, acceptance criteria, and allowable tolerances.
The following are the monographs can be consulted to ensure compliance with USP standards in UV/Vis spectroscopy.
