Description
CATO supplies Methyl 8,8-dioxo-8λ6-thia-2,3,5,7-tetraazatricyclo[7.4.0.0,2,6]trideca-1(13),3,5,9,11-pentaene-11-carboxylate (CAS 1354953-21-1), a certified reference material (molecular formula C10H8N4O4S, MW 280.26 g/mol) for analytical method development and quality control.
The molecular framework of Methyl 8,8-dioxo-8λ6-thia-2,3,5,7-tetraazatricyclo[7.4.0.0,2,6]trideca-1(13),3,5,9,11-pentaene-11-carboxylate (C10H8N4O4S) 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 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.
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.
