621-95-4 4,4'-Diaminodibenzyl Aniline, p,p'-ethylenedi- Benzenamine, 4,4'-(1,2-ethanediyl)bis- alpha,alpha'-Bi-p-toluidine (8CI) 4,4'-Ethylenebis(aniline) 4,4'-Ethylenedianiline 4-13-00-00401 (Beilstein Handbook Reference) Aniline, 4,4'-ethylenedi- 1,2-Bis(p-aminophenyl)ethane BRN 0394999 CCRIS 1004 4,4'-Diaminobibenzyl EINECS 210-716-7 NSC 44062 NSC 580 NSC 60033 EC 210-716-7 (C14H28N2) contains a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
