Chemical Structure

3-Ethoxydihydro-2H-pyran-4(3H)-one CAS 624734-18-5 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 144.17 g/mol gives 3-Ethoxydihydro-2H-pyran-4(3H)-one distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 3-Ethoxydihydro-2H-pyran-4(3H)-one (CAS 624734-18-5), a certified reference material (molecular formula C7H12O3, MW 144.17 g/mol) for analytical method development and quality control.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 3-Ethoxydihydro-2H-pyran-4(3H)-one is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 144.17 g/mol — guide the selection of appropriate sample preparation and analytical techniques.

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
