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 Fluralaner impurity 29.
As a process- or degradation-related impurity, Fluralaner impurity 29 (CAS CATO-C4X-218029, C18H11Cl2F3O3) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.
Based on its molecular formula C18H11Cl2F3O3, Fluralaner impurity 29 contains a steroid core, a hydroxyl group, an ether linkage, fluorine/chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 403.18 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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 Fluralaner impurity 29 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.
