Chemical Structure

1,1'-(((3,3'-Dimethyl-[1,1'-biphenyl]-4,4'-diyl)bis(azanylylidene))bis(methanylylidene))bis(naphthalen-2-ol) CAS 16196-97-7 chemical structure

Description

The molecular framework of 1,1'-(((3,3'-Dimethyl-[1,1'-biphenyl]-4,4'-diyl)bis(azanylylidene))bis(methanylylidene))bis(naphthalen-2-ol) (C36H28N2O2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. 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).

1,1'-(((3,3'-Dimethyl-[1,1'-biphenyl]-4,4'-diyl)bis(azanylylidene))bis(methanylylidene))bis(naphthalen-2-ol) (CAS 16196-97-7), molecular formula C36H28N2O2 and molecular weight 520.62 g/mol, is a CATO reference standard with documented purity and traceability.

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.
