Chemical Structure
Description
The occurrence of Mitomycin EP Impurity B (Mitomycin A) is closely related to a flavonoid core, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Mitomycin EP Impurity B (Mitomycin A) (CAS 4055-39-4), a pharmacopoeial impurity reference standard (molecular formula C16H19N3O6, MW 349.34 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C16H19N3O6, Mitomycin EP Impurity B (Mitomycin A) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 349.34 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
