Chemical Structure

Octadec-5-yn-1-ol CAS 676-43-7 chemical structure

Description

The occurrence of Octadec-5-yn-1-ol is closely related to a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Octadec-5-yn-1-ol (CAS 676-43-7), a certified reference material (molecular formula C18H34O, MW 266.46 g/mol) for analytical method development and quality control.

Structurally, Octadec-5-yn-1-ol (C18H34O) contains 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 266.46 g/mol, it falls into the medium-molecular-weight range. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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.
