(2S,3R)-2,3-Dihydroxy-4-(hydroxyamino)-4-oxobutyl dihydrogen phosphate (CAS 628339-03-7), molecular formula C4H10NO8P and molecular weight 231.10 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carbohydrate-derived structure, an amide group, a phosphate ester group, (2S,3R)-2,3-Dihydroxy-4-(hydroxyamino)-4-oxobutyl dihydrogen phosphate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 231.10 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.
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.
