Description
CATO supplies 8-(Ethylthio)-7-(2-hydroxy-2-(naphthalen-1-yloxy)ethyl)-3-methyl-3,7-dihydro-1H-purine-2,6-dione (CAS 303970-49-2), a certified reference material (molecular formula C20H20N4O4S, MW 412.46 g/mol) for analytical method development and quality control.
Structurally, 8-(Ethylthio)-7-(2-hydroxy-2-(naphthalen-1-yloxy)ethyl)-3-methyl-3,7-dihydro-1H-purine-2,6-dione (C20H20N4O4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 13.0, corresponding to approximately 13 ring(s) or double-bond equivalent(s). With a molecular weight of 412.46 g/mol, it falls into the moderately-high-molecular-weight range. 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.
