Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 252.27 g/mol gives 4,4'-(Buta-1,3-diyne-1,4-diyl)dibenzonitrile distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies 4,4'-(Buta-1,3-diyne-1,4-diyl)dibenzonitrile (CAS 103140-39-2), a certified reference material (molecular formula C18H8N2, MW 252.27 g/mol) for analytical method development and quality control.
The molecular framework of 4,4'-(Buta-1,3-diyne-1,4-diyl)dibenzonitrile (C18H8N2) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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), 4,4'-(Buta-1,3-diyne-1,4-diyl)dibenzonitrile 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.
