Chemical Structure
Description
As a certified reference material (CRM), Fluralaner Impurity 15 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
CATO supplies Fluralaner Impurity 15 (CAS 1805814-99-6), a pharmacopoeial impurity reference standard (molecular formula C22H17Cl2F6N3O3, MW 556.29 g/mol) used for the identification and quantification of trace impurities in APIs.
Fluralaner Impurity 15 (C22H17Cl2F6N3O3) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
