Brivaracetam Impurity 190 CAS CATO-C4X-2007190

Description

The occurrence of Brivaracetam Impurity 190 is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Brivaracetam Impurity 190 (CAS CATO-C4X-2007190), a pharmacopoeial impurity reference standard (molecular formula C11H18N2O3, MW 226.27 g/mol) used for the identification and quantification of trace impurities in APIs.

Based on its molecular formula C11H18N2O3, Brivaracetam Impurity 190 contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 226.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), Brivaracetam Impurity 190 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.
