4-(5-methylfuran-2-yl)but-3-en-2-one CAS 66434-99-9

Description

Compared with other compounds in its class, the molecular weight of 150.17 g/mol gives 4-(5-methylfuran-2-yl)but-3-en-2-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-(5-methylfuran-2-yl)but-3-en-2-one (CAS 66434-99-9), a certified reference material (molecular formula C9H10O2, MW 150.17 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 4-(5-methylfuran-2-yl)but-3-en-2-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 150.17 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.

As a certified reference material (CRM), 4-(5-methylfuran-2-yl)but-3-en-2-one meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
