cis-Epoxysuccinic Acid CAS 16533-72-5

Description

Compared with other compounds in its class, the molecular weight of 132.07 g/mol gives cis-Epoxysuccinic Acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

cis-Epoxysuccinic Acid (CAS 16533-72-5) is a high-purity analytical reference standard with the molecular formula C4H4O5 and a molecular weight of 132.07 g/mol.

Owing to a carbohydrate-derived structure, cis-Epoxysuccinic Acid is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 132.07 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).

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.
