Chemical Structure

Brivaracetam Impurity 162 CAS CATO-C4X-2007162 chemical structure

Description

The occurrence of Brivaracetam Impurity 162 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

Brivaracetam Impurity 162 (CAS CATO-C4X-2007162) is a certified pharmaceutical impurity reference standard with the molecular formula C9H16O4 and a molecular weight of 188.22 g/mol.

Structurally, Brivaracetam Impurity 162 (C9H16O4) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 188.22 g/mol, it falls into the medium-molecular-weight range.

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 162 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.
