4',4'''-(Thiophene-2,5-diyl)bis(([1,1'-biphenyl]-4-carbonitrile)) CAS 868403-91-2

Description

CATO supplies 4',4'''-(Thiophene-2,5-diyl)bis(([1,1'-biphenyl]-4-carbonitrile)) (CAS 868403-91-2), a certified reference material (molecular formula C30H18N2S, MW 438.54 g/mol) for analytical method development and quality control.

4',4'''-(Thiophene-2,5-diyl)bis(([1,1'-biphenyl]-4-carbonitrile)) (C30H18N2S) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.

The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
