Chemical Structure

2,6-Diethyl-3,5-dimethyl-4H-pyran-4-one CAS 1202-10-4 chemical structure

Description

2,6-Diethyl-3,5-dimethyl-4H-pyran-4-one (CAS 1202-10-4), molecular formula C11H16O2 and molecular weight 180.24 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 2,6-Diethyl-3,5-dimethyl-4H-pyran-4-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 180.24 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.
