Chemical Structure
Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies (2S,3S)-2-Amino-3-hydroxysuccinic acid hydrochloride (CAS 252580-11-3), a certified reference material (molecular formula C4H7NO5HCl, MW 185.56 g/mol) for analytical method development and quality control.
(2S,3S)-2-Amino-3-hydroxysuccinic acid hydrochloride (C4H7NO5HCl) contains a carbohydrate-derived structure, an amide 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.
