Chemical Structure
Description
Based on its molecular formula C18H20FNO3S, Prasugrel Impurity 37 contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 349.42 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.
Prasugrel Impurity 37 (CAS 866761-71-9) is a certified pharmaceutical impurity reference standard with the molecular formula C18H20FNO3S and a molecular weight of 349.42 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.
