Chemical Structure
Description
The occurrence of Brivaracetam Impurity 178 is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, iodine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Brivaracetam Impurity 178 (CAS CATO-C4X-2007178) is a certified pharmaceutical impurity reference standard with the molecular formula C9H17IO2 and a molecular weight of 284.13 g/mol.
Based on its molecular formula C9H17IO2, Brivaracetam Impurity 178 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 284.13 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.
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.
CATO manufactures Brivaracetam Impurity 178 under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
