Chemical Structure
Description
Based on its molecular formula C17H14ClN, Olmesartan Impurity 57 contains a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 267.75 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.
Olmesartan Impurity 57 (CAS CATO-C4X-109757) is a certified pharmaceutical impurity reference standard with the molecular formula C17H14ClN and a molecular weight of 267.75 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.
