Description
CATO supplies 3,3'-Diethyl-[1,1'-biphenyl]-4,4'-diamine (CAS 76787-87-6), a certified reference material (molecular formula C16H20N2, MW 240.34 g/mol) for analytical method development and quality control.
Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 3,3'-Diethyl-[1,1'-biphenyl]-4,4'-diamine is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 240.34 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 3,3'-Diethyl-[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.
