Chemical Structure

(1E,3E,5E,7E)-1,8-Diphenylocta-1,3,5,7-tetraene CAS 3029-40-1 chemical structure

Description

The molecular framework of (1E,3E,5E,7E)-1,8-Diphenylocta-1,3,5,7-tetraene (C20H18) is characterized by a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

(1E,3E,5E,7E)-1,8-Diphenylocta-1,3,5,7-tetraene (CAS 3029-40-1) is a high-purity analytical reference standard with the molecular formula C20H18 and a molecular weight of 258.36 g/mol.

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.
