As a process- or degradation-related impurity, SAR107375E Impurity 15 D11 (CAS CATO-C4X-229915, C24H19D11ClN5O5S2C4H6O6) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to deuterium isotope labeling, a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, SAR107375E Impurity 15 D11 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 729.26 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.
CATO manufactures SAR107375E Impurity 15 D11 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.
