Chemical Structure
Description
As a certified reference material (CRM), 3,3',5,5'-Tetraethyl-[1,1'-biphenyl]-4,4'-diamine 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.
CATO supplies 3,3',5,5'-Tetraethyl-[1,1'-biphenyl]-4,4'-diamine (CAS 2095-04-7), a certified reference material (molecular formula C20H28N2, MW 296.45 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 3,3',5,5'-Tetraethyl-[1,1'-biphenyl]-4,4'-diamine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 296.45 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
