Description

The occurrence of 2,2',7,7'-Tetra(pyridin-4-yl)-9,9'-spirobi[fluorene] 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',7,7'-Tetra(pyridin-4-yl)-9,9'-spirobi[fluorene] (CAS 1195403-94-1), a certified reference material (molecular formula C45H28N4, MW 624.73 g/mol) for analytical method development and quality control.

Structurally, 2,2',7,7'-Tetra(pyridin-4-yl)-9,9'-spirobi[fluorene] (C45H28N4) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. The molecule exhibits a degree of unsaturation (DBE) of 34.0, corresponding to approximately 34 ring(s) or double-bond equivalent(s). With a molecular weight of 624.73 g/mol, it falls into the high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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',7,7'-Tetra(pyridin-4-yl)-9,9'-spirobi[fluorene] 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.
