Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 585.49 g/mol gives Florfenicol Impurity 13 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Florfenicol Impurity 13 (CAS CATO-C4X-207513) is a certified pharmaceutical impurity reference standard with the molecular formula C22H27Cl2FN2O7S2 and a molecular weight of 585.49 g/mol.
Structurally, Florfenicol Impurity 13 (C22H27Cl2FN2O7S2) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 9.0, corresponding to approximately 9 ring(s) or double-bond equivalent(s). With a molecular weight of 585.49 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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 Florfenicol Impurity 13 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.
