Chemical Structure

2-Ethyl-2-methyl-2,3-dihydro-4H-pyran-4-one CAS 62322-08-1 chemical structure

Description

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 2-Ethyl-2-methyl-2,3-dihydro-4H-pyran-4-one is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 140.18 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).

2-Ethyl-2-methyl-2,3-dihydro-4H-pyran-4-one (CAS 62322-08-1) is a high-purity analytical reference standard with the molecular formula C8H12O2 and a molecular weight of 140.18 g/mol.

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.
