Chemical Structure
Description
The molecular framework of 2-Amino-3-(2-thioxo-2,3-dihydro-1H-imidazol-4-yl)propanoic acid (C6H9N3O2S) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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).
2-Amino-3-(2-thioxo-2,3-dihydro-1H-imidazol-4-yl)propanoic acid (CAS 13552-61-9), molecular formula C6H9N3O2S and molecular weight 187.22 g/mol, is a CATO reference standard with documented purity and traceability.
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.
