Chemical Structure

Ethyl 4,4-dimethoxy-3-oxobutanoate CAS 6956-50-9 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 190.19 g/mol gives Ethyl 4,4-dimethoxy-3-oxobutanoate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies Ethyl 4,4-dimethoxy-3-oxobutanoate (CAS 6956-50-9), a certified reference material (molecular formula C8H14O5, MW 190.19 g/mol) for analytical method development and quality control.

Structurally, Ethyl 4,4-dimethoxy-3-oxobutanoate (C8H14O5) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 190.19 g/mol, it falls into the medium-molecular-weight range.

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.
