Chemical Structure

Methyl 5-methyl-2-oxotetrahydrofuran-3-carboxylate CAS 74002-71-4 chemical structure

Description

Based on its molecular formula C7H10O4, Methyl 5-methyl-2-oxotetrahydrofuran-3-carboxylate contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 158.15 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).

CATO supplies Methyl 5-methyl-2-oxotetrahydrofuran-3-carboxylate (CAS 74002-71-4), a certified reference material (molecular formula C7H10O4, MW 158.15 g/mol) for analytical method development and quality control.
