Compared with other compounds in its class, the molecular weight of 284.39 g/mol gives Sulindac impurity 14 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Sulindac impurity 14 (CAS CATO-C4X-293014), a pharmacopoeial impurity reference standard (molecular formula C18H17FS, MW 284.39 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C18H17FS, Sulindac impurity 14 contains sulfur-containing functionality, fluorine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 284.39 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 manufactures Sulindac impurity 14 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.
