Description
Fluralaner Impurity 52 (CAS 1248658-92-5) is a certified pharmaceutical impurity reference standard with the molecular formula C6H8F6N2O and a molecular weight of 238.13 g/mol.
Owing to an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Fluralaner Impurity 52 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 238.13 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.
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.
CATO manufactures Fluralaner Impurity 52 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.
