Chemical Structure
Description
Structurally, 2-Ethyl-2,5-dihydro-4-hydroxy-3-methyl-5-oxo-2-furancarboxylic Acid Methyl Ester (C9H12O5) contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. The molecule exhibits a degree of unsaturation (DBE) of 4.0, corresponding to approximately 4 ring(s) or double-bond equivalent(s). With a molecular weight of 200.19 g/mol, it falls into the medium-molecular-weight range. 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).
