N,N'-Di(9-phenanthrenyl)-N,N'-diphenylbenzidine CAS 182507-83-1

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N,N'-Di(9-phenanthrenyl)-N,N'-diphenylbenzidine.

N,N'-Di(9-phenanthrenyl)-N,N'-diphenylbenzidine (CAS 182507-83-1), molecular formula C52H36N2 and molecular weight 688.86 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(9-phenanthrenyl)-N,N'-diphenylbenzidine is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 688.86 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.

CATO manufactures N,N'-Di(9-phenanthrenyl)-N,N'-diphenylbenzidine 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.
