Chemical Structure

(S)-Oxirane-2-carboxylic acid CAS 114990-90-8 chemical structure

Description

The occurrence of (S)-Oxirane-2-carboxylic acid is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(S)-Oxirane-2-carboxylic acid (CAS 114990-90-8), molecular formula C3H4O3 and molecular weight 88.06 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, (S)-Oxirane-2-carboxylic acid (C3H4O3) contains a carboxylic acid group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 2.0, corresponding to approximately 2 ring(s) or double-bond equivalent(s). With a molecular weight of 88.06 g/mol, it falls into the low-molecular-weight range.

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.
