Chemical Structure
Description
The occurrence of (4S,5S)-Methyl 4-amino-3-oxoisoxazolidine-5-carboxylate is closely related to a carbohydrate-derived structure, an amide group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(4S,5S)-Methyl 4-amino-3-oxoisoxazolidine-5-carboxylate (CAS 112244-07-2) is a high-purity analytical reference standard with the molecular formula C5H8N2O4 and a molecular weight of 160.13 g/mol.
(4S,5S)-Methyl 4-amino-3-oxoisoxazolidine-5-carboxylate (C5H8N2O4) contains a carbohydrate-derived structure, an amide 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.
