Chemical Structure

1-Ethyl 4-methyl 2-oxosuccinate CAS 174682-13-4 chemical structure

Description

1-Ethyl 4-methyl 2-oxosuccinate (C7H10O5) contains a carboxylic acid group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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).

1-Ethyl 4-methyl 2-oxosuccinate (CAS 174682-13-4) is a high-purity analytical reference standard with the molecular formula C7H10O5 and a molecular weight of 174.15 g/mol.

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.
