H96WTV8SM2 477-33-8 Samidin Crotonic acid, 3-methyl-, 9-ester with 9,10-dihydro-9,10-dihydroxy-8,8-dimethyl-2H,8H-benzo(1,2-b:3,4-b')-dipyran-2-one acetate (+)-Samidin UNII-H96WTV8SM2 (CAS 477-33-8) is a high-purity analytical reference standard with the molecular formula C21H28O7 and a molecular weight of 392.44 g/mol.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, H96WTV8SM2 477-33-8 Samidin Crotonic acid, 3-methyl-, 9-ester with 9,10-dihydro-9,10-dihydroxy-8,8-dimethyl-2H,8H-benzo(1,2-b:3,4-b')-dipyran-2-one acetate (+)-Samidin UNII-H96WTV8SM2 is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 392.44 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
