Description
As a certified reference material (CRM), [1,1'-Binaphthalene]-4,4'-dicarbonitrile 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.
[1,1'-Binaphthalene]-4,4'-dicarbonitrile (CAS 115584-22-0), molecular formula C22H12N2 and molecular weight 304.34 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of [1,1'-Binaphthalene]-4,4'-dicarbonitrile (C22H12N2) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. 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 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.
