Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies N,N-Dimethyl-4′-nitro[1,1′-biphenyl]-4-amine (CAS 2143-87-5), a certified reference material (molecular formula C14H14N2O2, MW 242.27 g/mol) for analytical method development and quality control.
N,N-Dimethyl-4′-nitro[1,1′-biphenyl]-4-amine (C14H14N2O2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
As a certified reference material (CRM), N,N-Dimethyl-4′-nitro[1,1′-biphenyl]-4-amine 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.
