Chemical Structure
Description
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.
(R)-3,3'-Bis(phenyl)-1,1'-bi-2-naphthol (CAS 75684-93-4), molecular formula C32H22O2 and molecular weight 438.52 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (R)-3,3'-Bis(phenyl)-1,1'-bi-2-naphthol (C32H22O2) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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), (R)-3,3'-Bis(phenyl)-1,1'-bi-2-naphthol 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.
