Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 269.32 g/mol gives SAR107375E Impurity 11 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
As a process- or degradation-related impurity, SAR107375E Impurity 11 (CAS CATO-C4X-229911, C12H15NO4S) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
SAR107375E Impurity 11 (C12H15NO4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 11 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.
