Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 206.21 g/mol gives Sulindac Impurity 9 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Sulindac Impurity 9 (CAS CATO-C4X-29309), a pharmacopoeial impurity reference standard (molecular formula C12H11FO2, MW 206.21 g/mol) used for the identification and quantification of trace impurities in APIs.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, fluorine substitution, an aromatic ring system, Sulindac Impurity 9 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 206.21 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), Sulindac Impurity 9 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
