Oxygen Impurities & Reference Standards

Oxygen is recognized as an active pharmaceutical ingredient (API) that supports formulation development, process validation, and quality assurance in drug manufacturing. Oxygen is registered under CAS Number 7782-44-7. It has a molecular formula of O2 and a molecular weight of 32.00 g/mol. Analytical laboratories rely on Oxygen and its associated impurity standards for method development, quality control testing, and pharmacopoeial compliance (ICH, USP, BP, EP). Oxygen is available as a certified impurity reference standard with CoA, HPLC chromatograms, and spectroscopic data to support analytical method development and regulatory compliance.
