6-Ethylbenzofuran-2(3H)-one CAS 742079-79-4

Description

The occurrence of 6-Ethylbenzofuran-2(3H)-one is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

6-Ethylbenzofuran-2(3H)-one (CAS 742079-79-4), molecular formula C10H10O2 and molecular weight 162.19 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C10H10O2, 6-Ethylbenzofuran-2(3H)-one contains a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 162.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
