1,8-Diphenyl-1,3,5,7-octatetrayne CAS 4572-12-7

Description

The occurrence of 1,8-Diphenyl-1,3,5,7-octatetrayne is closely related to a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1,8-Diphenyl-1,3,5,7-octatetrayne (CAS 4572-12-7), molecular formula C20H10 and molecular weight 250.29 g/mol, is a CATO reference standard with documented purity and traceability.

Based on its molecular formula C20H10, 1,8-Diphenyl-1,3,5,7-octatetrayne contains a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 250.29 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.
