Chemical Structure
Description
The occurrence of (S)-3-Amino-4-oxo-4-(phosphonooxy)butanoic acid is closely related to a carbohydrate-derived structure, an amide group, a phosphate ester group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(S)-3-Amino-4-oxo-4-(phosphonooxy)butanoic acid (CAS 77815-87-3) is a high-purity analytical reference standard with the molecular formula C4H8NO7P and a molecular weight of 213.08 g/mol.
(S)-3-Amino-4-oxo-4-(phosphonooxy)butanoic acid (C4H8NO7P) contains a carbohydrate-derived structure, an amide group, a phosphate ester group. It is notably hygroscopic, 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.
