Chemical Structure
Description
Owing to a steroid core, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution, Sulindac impurity 15 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 340.41 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.
As a process- or degradation-related impurity, Sulindac impurity 15 (CAS CATO-C4X-293015, C20H17FO2S) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
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 15 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.
