Brivaracetam Impurity 91 CAS CATO-C4X-200791

Description

The occurrence of Brivaracetam Impurity 91 is closely related to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

As a process- or degradation-related impurity, Brivaracetam Impurity 91 (CAS CATO-C4X-200791, C15H30N4O3) is essential for impurity profiling, related-substances testing, and forced-degradation studies in pharmaceutical development.

Owing to an amide group, a carboxylic acid group, a hydroxyl group, an ether linkage, Brivaracetam Impurity 91 is typically white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 314.42 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.

This reference standard supports related-substances testing and method development in line with ICH Q3A/Q3B guidance on impurity control, and is suitable for system suitability testing and forced-degradation studies.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
