Description
CATO manufactures Sitafloxacin impurity 78 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.
Sitafloxacin impurity 78 (CAS CATO-C4X-115578) is a certified pharmaceutical impurity reference standard with the molecular formula C23H26ClF2N3O3 and a molecular weight of 465.92 g/mol.
Based on its molecular formula C23H26ClF2N3O3, Sitafloxacin impurity 78 contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 465.92 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
