Chemical Structure
Description
The occurrence of 3,4-Dihydroxy-5-methylfuran-2(5H)-one is closely related to a carbohydrate-derived structure in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 3,4-Dihydroxy-5-methylfuran-2(5H)-one (CAS 3566-57-2), a certified reference material (molecular formula C5H6O4, MW 130.10 g/mol) for analytical method development and quality control.
Owing to a carbohydrate-derived structure, 3,4-Dihydroxy-5-methylfuran-2(5H)-one is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 130.10 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
