Brivaracetam Impurity 33 CAS CATO-C4X-200733 chemical structure

Description

Brivaracetam Impurity 33 (CAS CATO-C4X-200733) is a certified pharmaceutical impurity reference standard with the molecular formula C7H13IO2 and a molecular weight of 256.08 g/mol.

Based on its molecular formula C7H13IO2, Brivaracetam Impurity 33 contains a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 256.08 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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 33 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.
