Brivaracetam Impurity 139 CAS CATO-C4X-2007139

Description

Compared with other compounds in its class, the molecular weight of 268.15 g/mol gives Brivaracetam Impurity 139 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Brivaracetam Impurity 139 (CAS CATO-C4X-2007139) is a certified pharmaceutical impurity reference standard with the molecular formula C8H17N3O2HBr and a molecular weight of 268.15 g/mol.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, bromine substitution, Brivaracetam Impurity 139 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 268.15 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures Brivaracetam Impurity 139 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
