Chemical Structure
Description
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.
4-((1,1-Dioxidotetrahydro-2H-thiopyran-4-yl)amino)but-2-enoic acid (CAS 1704271-84-0), molecular formula C9H15NO4S and molecular weight 233.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-((1,1-Dioxidotetrahydro-2H-thiopyran-4-yl)amino)but-2-enoic acid (C9H15NO4S) is characterized by an amide group, a sulfone group, a carboxylic acid 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 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.
