Description
CATO manufactures Travoprost Impurity 38 Sodium Salt 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.
CATO supplies Travoprost Impurity 38 Sodium Salt (CAS CATO-C4X-192538), a pharmacopoeial impurity reference standard (molecular formula C25H24F3O7.Na, MW 516.45 g/mol) used for the identification and quantification of trace impurities in APIs.
Structurally, Travoprost Impurity 38 Sodium Salt (C25H24F3O7.Na) contains a flavonoid core, a hydroxyl group, an ether linkage, fluorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 12.5, corresponding to approximately 12 ring(s) or double-bond equivalent(s). With a molecular weight of 516.45 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
