2-(3-Hexynyloxy)tetrahydro-2H-pyran CAS 70482-82-5

Description

The occurrence of 2-(3-Hexynyloxy)tetrahydro-2H-pyran 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.

2-(3-Hexynyloxy)tetrahydro-2H-pyran (CAS 70482-82-5) is a high-purity analytical reference standard with the molecular formula C11H18O2 and a molecular weight of 182.26 g/mol.

Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, 2-(3-Hexynyloxy)tetrahydro-2H-pyran is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 182.26 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.
