Chemical Structure
Description
Based on its molecular formula C16H15Cl2NO4, Clevidipine Butyrate impurity 17 contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 356.20 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.
CATO supplies Clevidipine Butyrate impurity 17 (CAS 123853-39-4), a pharmacopoeial impurity reference standard (molecular formula C16H15Cl2NO4, MW 356.20 g/mol) used for the identification and quantification of trace impurities in APIs.
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.
