Chemical Structure
Description
Based on its molecular formula C15H26BClO2, Bortezomib Impurity N46 contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic functional-group stretching vibrations in infrared spectroscopy. The molecular weight of 284.63 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Bortezomib Impurity N46 (CAS 85167-14-2) is a certified pharmaceutical impurity reference standard with the molecular formula C15H26BClO2 and a molecular weight of 284.63 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.
