40817-08-1 4-Cyano-4'-pentylbiphenyl (1,1'-Biphenyl)-4-carbonitrile, 4'-pentyl- 4'-Pentyl(1,1'-biphenyl)-4-carbonitrile p-Cyano-p'-pentylbiphenyl EINECS 255-093-2 PCB (CAS 40817-08-1) is a high-purity analytical reference standard with the molecular formula C18H31N and a molecular weight of 261.45 g/mol.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 40817-08-1 4-Cyano-4'-pentylbiphenyl (1,1'-Biphenyl)-4-carbonitrile, 4'-pentyl- 4'-Pentyl(1,1'-biphenyl)-4-carbonitrile p-Cyano-p'-pentylbiphenyl EINECS 255-093-2 PCB is typically off-white to pale yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 261.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
