The occurrence of Cidofovir Impurity 1 is closely related to an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies Cidofovir Impurity 1 (CAS 133868-60-7), a pharmacopoeial impurity reference standard (molecular formula C8H14N3O6P, MW 279.19 g/mol) used for the identification and quantification of trace impurities in APIs.
Based on its molecular formula C8H14N3O6P, Cidofovir Impurity 1 contains an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 279.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
