Epinastine Impurity N6 CAS 339163-80-3 chemical structure

Description

CATO supplies Epinastine Impurity N6 (CAS 339163-80-3), a pharmacopoeial impurity reference standard (molecular formula C15H14N2, MW 222.29 g/mol) used for the identification and quantification of trace impurities in APIs.

Epinastine Impurity N6 (C15H14N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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.

As a certified reference material (CRM), Epinastine Impurity N6 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.
