Chemical Structure

Brivaracetam Impurity 88 CAS 2096999-79-8 chemical structure

Description

Brivaracetam Impurity 88 (C7H13O3Na) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

CATO supplies Brivaracetam Impurity 88 (CAS 2096999-79-8), a pharmacopoeial impurity reference standard (molecular formula C7H13O3Na, MW 168.17 g/mol) used for the identification and quantification of trace impurities in APIs.

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.
