Cyclophosphamide Impurity 5 CAS 90632-33-0

Description

Compared with other compounds in its class, the molecular weight of 224.19 g/mol gives Cyclophosphamide Impurity 5 distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Cyclophosphamide Impurity 5 (CAS 90632-33-0) is a certified pharmaceutical impurity reference standard with the molecular formula C7H17N2O4P and a molecular weight of 224.19 g/mol.

Owing to an amide group, a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, Cyclophosphamide Impurity 5 is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 224.19 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
