Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including N4,N4'-Diethyl-[1,1'-biphenyl]-4,4'-diamine.
CATO supplies N4,N4'-Diethyl-[1,1'-biphenyl]-4,4'-diamine (CAS 6290-86-4), a certified reference material (molecular formula C10H13Cl2O2PS, MW 299.15 g/mol) for analytical method development and quality control.
Owing to a sulfone group, organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, N4,N4'-Diethyl-[1,1'-biphenyl]-4,4'-diamine is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 299.15 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.
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), N4,N4'-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.
