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 25.
Fluralaner Impurity 25 (CAS 1805814-97-4) is a certified pharmaceutical impurity reference standard with the molecular formula C26H17ClF9N3O3 and a molecular weight of 625.87 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, Fluralaner Impurity 25 is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 625.87 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 Fluralaner Impurity 25 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.
