Chemical Structure
Description
Based on its molecular formula C9H22ClN2O4P, Cyclophosphamide impurity 37 contains an amide group, a phosphate ester group, 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 288.71 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.
Cyclophosphamide impurity 37 (CAS CATO-C4X-230637) is a certified pharmaceutical impurity reference standard with the molecular formula C9H22ClN2O4P and a molecular weight of 288.71 g/mol.
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.
