The occurrence of (2S,3S,4R,5S,6S)-2-Ethynyl-6-(methoxycarbonyl)tetrahydro-2H-pyran-3,4,5-triyl triacetate is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(2S,3S,4R,5S,6S)-2-Ethynyl-6-(methoxycarbonyl)tetrahydro-2H-pyran-3,4,5-triyl triacetate (CAS 2563871-46-3) is a high-purity analytical reference standard with the molecular formula C15H18O9 and a molecular weight of 342.30 g/mol.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, (2S,3S,4R,5S,6S)-2-Ethynyl-6-(methoxycarbonyl)tetrahydro-2H-pyran-3,4,5-triyl triacetate is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 342.30 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).
