Chemical Structure

N,N'-bis(phenanthren-9-yl)-N,N'-bis(phenyl)-benzidine CAS 934000-87-0 chemical structure

Description

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.

N,N'-bis(phenanthren-9-yl)-N,N'-bis(phenyl)-benzidine (CAS 934000-87-0), molecular formula C52H36N2 and molecular weight 688.86 g/mol, is a CATO reference standard with documented purity and traceability.

N,N'-bis(phenanthren-9-yl)-N,N'-bis(phenyl)-benzidine (C52H36N2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
