Chemical Structure

1-(4-Ethoxy-3-methoxyphenyl)ethanone CAS 75665-89-3 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 194.23 g/mol gives 1-(4-Ethoxy-3-methoxyphenyl)ethanone distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 1-(4-Ethoxy-3-methoxyphenyl)ethanone (CAS 75665-89-3), a certified reference material (molecular formula C11H14O3, MW 194.23 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, 1-(4-Ethoxy-3-methoxyphenyl)ethanone is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 194.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
