Naltrexone impurity F is a defined impurity reference material with a minimum purity of 95 %, intended for analytical and pharmaceutical research. It is identified by CAS number 2397651-97-5, carries the empirical formula C₂₀H₂₃NO₅ and has a molar mass of 357,4 g/mol. Analytical laboratories use such standards for HPLC and LC-MS calibration, system suitability checks and comparative quantification against the parent active substance. The clearly stated identity and assay level help laboratories build reproducible impurity control strategies and regulatory documentation. This biochemical impurity standard from manufacturer Carl ROTH fits workflows that demand traceable chemical identity together with a specified minimum purity. Its compact pack size is practical for reference libraries, validation studies and routine monitoring of naltrexone-related process or degradation impurities in research and development settings. This article is part of Chromatography standards (GC, HPLC, pesticides), in Analytical standards & reference materials.
