Description
As a certified reference material (CRM), 4-([1,1'-Biphenyl]-2-yloxy)aniline 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.
4-([1,1'-Biphenyl]-2-yloxy)aniline (CAS 212189-56-5) is a high-purity analytical reference standard with the molecular formula C18H15NO and a molecular weight of 261.32 g/mol.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, 4-([1,1'-Biphenyl]-2-yloxy)aniline is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 261.32 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
