Chemical Structure
Description
(S)-2-Amino-2-(5-oxo-2,5-dihydroisoxazol-4-yl)acetic acid (CAS 130620-57-4), molecular formula C5H6N2O4 and molecular weight 158.11 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (S)-2-Amino-2-(5-oxo-2,5-dihydroisoxazol-4-yl)acetic acid (C5H6N2O4) is characterized by a carbohydrate-derived structure, an amide group. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures (S)-2-Amino-2-(5-oxo-2,5-dihydroisoxazol-4-yl)acetic 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.
