(S)-2-Amino-3-(3-hydroxy-4-methylisoxazol-5-yl)propanoic acid CAS 211191-53-6

Description

Compared with other compounds in its class, the molecular weight of 186.17 g/mol gives (S)-2-Amino-3-(3-hydroxy-4-methylisoxazol-5-yl)propanoic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies (S)-2-Amino-3-(3-hydroxy-4-methylisoxazol-5-yl)propanoic acid (CAS 211191-53-6), a certified reference material (molecular formula C7H10N2O4, MW 186.17 g/mol) for analytical method development and quality control.

The molecular framework of (S)-2-Amino-3-(3-hydroxy-4-methylisoxazol-5-yl)propanoic acid (C7H10N2O4) 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

CATO manufactures (S)-2-Amino-3-(3-hydroxy-4-methylisoxazol-5-yl)propanoic acid under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
