Chemical Structure

2-Ethynyl-6-methylphenol CAS 99299-72-6 chemical structure

Description

The occurrence of 2-Ethynyl-6-methylphenol is closely related to a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

2-Ethynyl-6-methylphenol (CAS 99299-72-6), molecular formula C9H8O and molecular weight 132.16 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a hydroxyl group, an ether linkage, an aromatic ring system, 2-Ethynyl-6-methylphenol is typically off-white to pale yellow liquid. Its solid-state physicochemical attributes — including a molecular weight of 132.16 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.

As a certified reference material (CRM), 2-Ethynyl-6-methylphenol 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.
