Description
Fluralaner-13C2-d2-15N (CAS CATO-C4X-21801), molecular formula C20[13C]2H15D2Cl2F6N2[15N]O3 and molecular weight 561.28 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, Fluralaner-13C2-d2-15N is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 561.28 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Fluralaner-13C2-d2-15N 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.
