((1Z,3Z)-1,2,3,4-Tetraphenylbuta-1,3-diene-1,4-diyl)bis(diphenylphosphine) CAS 420120-75-8

Description

((1Z,3Z)-1,2,3,4-Tetraphenylbuta-1,3-diene-1,4-diyl)bis(diphenylphosphine) (CAS 420120-75-8) is a high-purity analytical reference standard with the molecular formula C52H40P2 and a molecular weight of 726.82 g/mol.

Owing to organophosphorus functionality, a polycyclic aromatic system, ((1Z,3Z)-1,2,3,4-Tetraphenylbuta-1,3-diene-1,4-diyl)bis(diphenylphosphine) is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 726.82 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
