Chemical Structure

Brivaracetam Impurity 24 CAS 93554-80-4 chemical structure

Description

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 supplies Brivaracetam Impurity 24 (CAS 93554-80-4), a pharmacopoeial impurity reference standard (molecular formula C4H8N2HCl, MW 120.58 g/mol) used for the identification and quantification of trace impurities in APIs.

Brivaracetam Impurity 24 (C4H8N2HCl) contains chlorine substitution. Halogen substitution raises its density and boiling point; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
