CATO supplies Phosphorylcholine (CAS 107-73-3), a certified reference material (molecular formula C5H15NO4PCl, MW 219.60 g/mol) for analytical method development and quality control.
Phosphorylcholine (C5H15NO4PCl) contains a carbohydrate-derived structure, an amide group, a phosphate ester group, 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
