(R)-2,2'-Dimethoxy-3,3'-diphenyl-1,1'-binaphthalene (CAS 219757-68-3), molecular formula C34H26O2 and molecular weight 466.57 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system, (R)-2,2'-Dimethoxy-3,3'-diphenyl-1,1'-binaphthalene is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 466.57 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).
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.
As a certified reference material (CRM), (R)-2,2'-Dimethoxy-3,3'-diphenyl-1,1'-binaphthalene 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.
