Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 204.18 g/mol gives (R)-2-Amino-3-(3-hydroxy-4-methylisoxazol-5-yl)propanoic acid hydrate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
(R)-2-Amino-3-(3-hydroxy-4-methylisoxazol-5-yl)propanoic acid hydrate (CAS 210049-09-5) is a high-purity analytical reference standard with the molecular formula C7H10N2O4H2O and a molecular weight of 204.18 g/mol.
The molecular framework of (R)-2-Amino-3-(3-hydroxy-4-methylisoxazol-5-yl)propanoic acid hydrate (C7H10N2O4H2O) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
