Chemical Structure

Ethylmalonic Acid CAS 601-75-2 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 132.11 g/mol gives Ethylmalonic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

Ethylmalonic Acid (CAS 601-75-2), molecular formula C5H8O4 and molecular weight 132.11 g/mol, is a CATO reference standard with documented purity and traceability.

Ethylmalonic Acid (C5H8O4) contains a carbohydrate-derived structure. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions.

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.
