N,N′-Di(2-naphthyl-N,N′-diphenyl)-1,1′-biphenyl-4,4′-diamine, 97% CAS 139255-17-7

Description

CATO manufactures N,N′-Di(2-naphthyl-N,N′-diphenyl)-1,1′-biphenyl-4,4′-diamine, 97% under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.

N,N′-Di(2-naphthyl-N,N′-diphenyl)-1,1′-biphenyl-4,4′-diamine, 97% (CAS 139255-17-7), molecular formula C44H32N2 and molecular weight 588.74 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, N,N′-Di(2-naphthyl-N,N′-diphenyl)-1,1′-biphenyl-4,4′-diamine, 97% is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 588.74 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
