Chemical Structure

5-Methyl-3-methylenedihydrofuran-2(3H)-one CAS 62873-16-9 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies 5-Methyl-3-methylenedihydrofuran-2(3H)-one (CAS 62873-16-9), a certified reference material (molecular formula C6H8O2, MW 112.13 g/mol) for analytical method development and quality control.

The molecular framework of 5-Methyl-3-methylenedihydrofuran-2(3H)-one (C6H8O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).

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.
