Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 392.66 g/mol gives Florfenicol Impurity 8 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
Florfenicol Impurity 8 (CAS CATO-C4X-20758) is a certified pharmaceutical impurity reference standard with the molecular formula C12H13Cl3FNO4S and a molecular weight of 392.66 g/mol.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, Florfenicol Impurity 8 is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 392.66 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 Florfenicol Impurity 8 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.
