Description
CATO supplies (4AS,8R,8aS)-8a-acetyl-6-methyl-4-oxo-2-pivalamido-1,4,4a,5,8,8a-hexahydroquinazolin-8-yl acetate (CAS 87037-52-3), a certified reference material (molecular formula C18H25N3O5, MW 363.41 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, (4AS,8R,8aS)-8a-acetyl-6-methyl-4-oxo-2-pivalamido-1,4,4a,5,8,8a-hexahydroquinazolin-8-yl acetate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 363.41 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.
