Chemical Structure
Description
1-Allyl-2-imino-3-(phenylsulfonyl)-1H-dipyrido[1,2-a:2',3'-d]pyrimidin-5(2H)-one (CAS 489464-54-2) is a high-purity analytical reference standard with the molecular formula C20H16N4O3S and a molecular weight of 392.43 g/mol.
Owing to a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, 1-Allyl-2-imino-3-(phenylsulfonyl)-1H-dipyrido[1,2-a:2',3'-d]pyrimidin-5(2H)-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 392.43 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
