Chemical Structure

Fluralaner Impurity 63 CAS 3027861-23-7 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 543.34 g/mol gives Fluralaner Impurity 63 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Fluralaner Impurity 63 (CAS 3027861-23-7) is a certified pharmaceutical impurity reference standard with the molecular formula C24H20Cl2F4N4O2 and a molecular weight of 543.34 g/mol.

Structurally, Fluralaner Impurity 63 (C24H20Cl2F4N4O2) contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 14.0, corresponding to approximately 14 ring(s) or double-bond equivalent(s). With a molecular weight of 543.34 g/mol, it falls into the moderately-high-molecular-weight range. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

As a certified reference material (CRM), Fluralaner Impurity 63 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.
