Description
CATO manufactures Cefdinir CP Impurity S 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.
As a process- or degradation-related impurity, Cefdinir CP Impurity S (CAS 127770-93-8, C16H15N5O6S2) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Cefdinir CP Impurity S is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 437.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
