Chemical Structure
Description
The occurrence of 5,6-Dihydro-2H-pyran-3-carboxaldehyde is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
5,6-Dihydro-2H-pyran-3-carboxaldehyde (CAS 13417-49-7) is a high-purity analytical reference standard with the molecular formula C6H8O2 and a molecular weight of 112.13 g/mol.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 5,6-Dihydro-2H-pyran-3-carboxaldehyde is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 112.13 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).
