Chemical Structure

Mesaconic Acid CAS 498-24-8 chemical structure

Description

Mesaconic Acid (CAS 498-24-8) is a high-purity analytical reference standard with the molecular formula C5H6O4 and a molecular weight of 130.10 g/mol.

Owing to a carbohydrate-derived structure, Mesaconic Acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 130.10 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).

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.
