Chemical Structure
Description
4-ethyl-4H,5H,6H,7H-[1,2,5]selenadiazolo[3,4-d]pyrimidine-5,7-dione (CAS 2934736-74-8), molecular formula C6H6N4O2Se and molecular weight 245.10 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-ethyl-4H,5H,6H,7H-[1,2,5]selenadiazolo[3,4-d]pyrimidine-5,7-dione (C6H6N4O2Se) is characterized by an amino-acid-derived structure, an amide 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.
