CATO supplies 65181-78-4 (1,1'-Biphenyl)-4,4'-diamine, N4,N4'-bis(3-methylphenyl)-N4,N4'-diphenyl- (1,1'-Biphenyl)-4,4'-diamine, N,N'-bis(3-methylphenyl)-N,N'-diphenyl- N,N'-Diphenyl-N,N'-bis(3-methylphenyl)-(1,1'-diphenyl)-4,4'-diamine N,N'-Bis(3-methylphenyl)-N,N'-diphenyl-(1,1'-biphenyl)-4,4'-diamine EC 413-810-8 (CAS 65181-78-4), a certified reference material (molecular formula C38H68N2, MW 552.96 g/mol) for analytical method development and quality control.
Structurally, 65181-78-4 (1,1'-Biphenyl)-4,4'-diamine, N4,N4'-bis(3-methylphenyl)-N4,N4'-diphenyl- (1,1'-Biphenyl)-4,4'-diamine, N,N'-bis(3-methylphenyl)-N,N'-diphenyl- N,N'-Diphenyl-N,N'-bis(3-methylphenyl)-(1,1'-diphenyl)-4,4'-diamine N,N'-Bis(3-methylphenyl)-N,N'-diphenyl-(1,1'-biphenyl)-4,4'-diamine EC 413-810-8 (C38H68N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 6.0, corresponding to approximately 6 ring(s) or double-bond equivalent(s). With a molecular weight of 552.96 g/mol, it falls into the moderately-high-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.
