Chemical Structure
Description
Methyl 2-{4-[(4-methoxyphenyl)sulfonyl]-3,4-dihydro-2H-1,4-benzoxazin-3-yl}acetate (CAS 439107-36-5) is a high-purity analytical reference standard with the molecular formula C18H19NO6S and a molecular weight of 377.41 g/mol.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, Methyl 2-{4-[(4-methoxyphenyl)sulfonyl]-3,4-dihydro-2H-1,4-benzoxazin-3-yl}acetate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 377.41 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.
