CATO supplies 4488-22-6 TL35MU1249 2,2'-Diamino-1,1'-dinaphthyl (1,1'-Binaphthalene)-2,2'-diamine 4-13-00-00489 (Beilstein Handbook Reference) 1,1'-Bi(2-naphthalenylamine) 1,1'-Bi(2-naphthylamine) BRN 2138401 NSC 519704 UNII-TL35MU1249 (CAS 4488-22-6), a certified reference material (molecular formula C20H36N2, MW 304.51 g/mol) for analytical method development and quality control.

The molecular framework of 4488-22-6 TL35MU1249 2,2'-Diamino-1,1'-dinaphthyl (1,1'-Binaphthalene)-2,2'-diamine 4-13-00-00489 (Beilstein Handbook Reference) 1,1'-Bi(2-naphthalenylamine) 1,1'-Bi(2-naphthylamine) BRN 2138401 NSC 519704 UNII-TL35MU1249 (C20H36N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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 presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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.
