Chemical Structure

Sitafloxacin Impurity 83 CAS CATO-C4X-115583 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including Sitafloxacin Impurity 83.

CATO supplies Sitafloxacin Impurity 83 (CAS CATO-C4X-115583), a pharmacopoeial impurity reference standard (molecular formula C32H24Cl2F4N4O6, MW 707.46 g/mol) used for the identification and quantification of trace impurities in APIs.

Structurally, Sitafloxacin Impurity 83 (C32H24Cl2F4N4O6) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 20.0, corresponding to approximately 20 ring(s) or double-bond equivalent(s). With a molecular weight of 707.46 g/mol, it falls into the high-molecular-weight range. 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 Sitafloxacin Impurity 83 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.
