Chemical Structure

Brivaracetam Impurity 195 CAS CATO-C4X-2007195 chemical structure

Description

Structurally, Brivaracetam Impurity 195 (C4H8N2HCl) contains chlorine substitution. The molecule exhibits a degree of unsaturation (DBE) of 1.0, corresponding to approximately 1 ring(s) or double-bond equivalent(s). With a molecular weight of 120.58 g/mol, it falls into the low-molecular-weight range. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Brivaracetam Impurity 195 (CAS CATO-C4X-2007195) is a certified pharmaceutical impurity reference standard with the molecular formula C4H8N2HCl and a molecular weight of 120.58 g/mol.

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.
