Chemical Structure

(2S)-2-ethynyloxolane CAS 1398833-76-5 chemical structure

Description

Owing to a hydroxyl group, an ether linkage, (2S)-2-ethynyloxolane is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 96.13 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).

(2S)-2-ethynyloxolane (CAS 1398833-76-5), molecular formula C6H8O and molecular weight 96.13 g/mol, is a CATO reference standard with documented purity and traceability.

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.

As a certified reference material (CRM), (2S)-2-ethynyloxolane meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
