1-(Trans-2-Phenylethenyl)-4-(phenylethynyl)benzene CAS 173035-17-1

Description

The occurrence of 1-(Trans-2-Phenylethenyl)-4-(phenylethynyl)benzene is closely related to a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

1-(Trans-2-Phenylethenyl)-4-(phenylethynyl)benzene (CAS 173035-17-1), molecular formula C22H16 and molecular weight 280.36 g/mol, is a CATO reference standard with documented purity and traceability.

Structurally, 1-(Trans-2-Phenylethenyl)-4-(phenylethynyl)benzene (C22H16) contains a polycyclic aromatic system. The molecule exhibits a degree of unsaturation (DBE) of 15.0, corresponding to approximately 15 ring(s) or double-bond equivalent(s). With a molecular weight of 280.36 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.
