2,2'-((1E,1'E)-(((1S,2S)-1,2-Diphenylethane-1,2-diyl)bis(azanylylidene))bis(methanylylidene))diphenol CAS 177770-03-5

Description

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.

2,2'-((1E,1'E)-(((1S,2S)-1,2-Diphenylethane-1,2-diyl)bis(azanylylidene))bis(methanylylidene))diphenol (CAS 177770-03-5) is a high-purity analytical reference standard with the molecular formula C28H24N2O2 and a molecular weight of 420.50 g/mol.

Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 2,2'-((1E,1'E)-(((1S,2S)-1,2-Diphenylethane-1,2-diyl)bis(azanylylidene))bis(methanylylidene))diphenol is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 420.50 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).
