Chemical Structure
Description
The occurrence of 2-ethynylbenzyl alcohol is closely related to a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
2-ethynylbenzyl alcohol (CAS 10602-08-1) is a high-purity analytical reference standard with the molecular formula C9H14O and a molecular weight of 138.21 g/mol.
Owing to a hydroxyl group, an ether linkage, 2-ethynylbenzyl alcohol is typically white to off-white liquid. Its solid-state physicochemical attributes — including a molecular weight of 138.21 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 2-ethynylbenzyl alcohol 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.
