Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 261.09 g/mol gives Cyclophosphamide distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Cyclophosphamide (CAS 50-18-0), a certified reference material (molecular formula C7H15Cl2N2O2P, MW 261.09 g/mol) for analytical method development and quality control.
Cyclophosphamide (C7H15Cl2N2O2P) contains an amide group, organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution. It is notably hygroscopic, halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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 analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
