Chemical Structure
Description
The occurrence of 3-(Hydroxymethyl)furan-2(5H)-one 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.
3-(Hydroxymethyl)furan-2(5H)-one (CAS 109765-92-6), molecular formula C5H6O3 and molecular weight 114.10 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 3-(Hydroxymethyl)furan-2(5H)-one is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 114.10 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.
