5-Hydroxy-3,4:7,8-dibenzocyclooct-1-yne CAS 1027338-06-2

Description

The occurrence of 5-Hydroxy-3,4:7,8-dibenzocyclooct-1-yne is closely related to a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 5-Hydroxy-3,4:7,8-dibenzocyclooct-1-yne (CAS 1027338-06-2), a certified reference material (molecular formula C16H12O, MW 220.27 g/mol) for analytical method development and quality control.

Based on its molecular formula C16H12O, 5-Hydroxy-3,4:7,8-dibenzocyclooct-1-yne contains a hydroxyl group, an ether linkage, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 220.27 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
