N4-(6-(4-Chlorophenyl)pyridazin-3-yl)-[1,1'-biphenyl]-4,4'-diamine CAS 901773-91-9

Description

N4-(6-(4-Chlorophenyl)pyridazin-3-yl)-[1,1'-biphenyl]-4,4'-diamine (CAS 901773-91-9) is a high-purity analytical reference standard with the molecular formula C22H17ClN4 and a molecular weight of 372.85 g/mol.

The molecular framework of N4-(6-(4-Chlorophenyl)pyridazin-3-yl)-[1,1'-biphenyl]-4,4'-diamine (C22H17ClN4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
