Chemical Structure

(2S,3S)-2,3-Oxiranedicarboxylic Acid Monoethyl Ester CAS 89886-73-7 chemical structure

Description

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.

(2S,3S)-2,3-Oxiranedicarboxylic Acid Monoethyl Ester (CAS 89886-73-7), molecular formula C6H8O5 and molecular weight 160.12 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (2S,3S)-2,3-Oxiranedicarboxylic Acid Monoethyl Ester (C6H8O5) contains a carbohydrate-derived structure. The molecule exhibits a degree of unsaturation (DBE) of 3.0, corresponding to approximately 3 ring(s) or double-bond equivalent(s). With a molecular weight of 160.12 g/mol, it falls into the medium-molecular-weight range. 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.
