4,4'-(2,2',2",5,5',5"-Hexamethyl-[1,1':4',1"-terphenyl]-4,4"-diyl)dipyridine CAS 1482505-91-8

Description

CATO supplies 4,4'-(2,2',2",5,5',5"-Hexamethyl-[1,1':4',1"-terphenyl]-4,4"-diyl)dipyridine (CAS 1482505-91-8), a certified reference material (molecular formula C34H32N2, MW 468.63 g/mol) for analytical method development and quality control.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 4,4'-(2,2',2",5,5',5"-Hexamethyl-[1,1':4',1"-terphenyl]-4,4"-diyl)dipyridine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 468.63 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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), 4,4'-(2,2',2",5,5',5"-Hexamethyl-[1,1':4',1"-terphenyl]-4,4"-diyl)dipyridine 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.
