Chemical Structure

5-Methylfuran-2(5H)-one CAS 591-11-7 chemical structure

Description

CATO manufactures 5-Methylfuran-2(5H)-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

CATO supplies 5-Methylfuran-2(5H)-one (CAS 591-11-7), a certified reference material (molecular formula C5H6O2, MW 98.10 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 5-Methylfuran-2(5H)-one is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 98.10 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.
