Chemical Structure
Description
5-((4-Methylthiazol-2-yl)amino)-5-oxopentanoic acid (CAS 353779-69-8), molecular formula C9H12N2O3S and molecular weight 228.27 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 5-((4-Methylthiazol-2-yl)amino)-5-oxopentanoic acid (C9H12N2O3S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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).
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.
