2,2'-Bis(diphenylamino)-9,9'-spirobifluorene CAS 862664-73-1

Description

The occurrence of 2,2'-Bis(diphenylamino)-9,9'-spirobifluorene is closely related to a nitrogen-containing heterocyclic scaffold, a nitrile group in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies 2,2'-Bis(diphenylamino)-9,9'-spirobifluorene (CAS 862664-73-1), a certified reference material (molecular formula C49H34N2, MW 650.81 g/mol) for analytical method development and quality control.

Based on its molecular formula C49H34N2, 2,2'-Bis(diphenylamino)-9,9'-spirobifluorene contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 650.81 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.

As a certified reference material (CRM), 2,2'-Bis(diphenylamino)-9,9'-spirobifluorene meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
