This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.
CATO supplies (1R,2S,5S)-Emtricitabine Impurity N9 (CAS 20752-33-4), a pharmacopoeial impurity reference standard (molecular formula C10H20O, MW 156.27 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a hydroxyl group, an ether linkage, (1R,2S,5S)-Emtricitabine Impurity N9 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 156.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO manufactures (1R,2S,5S)-Emtricitabine Impurity N9 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
