Chemical Structure
Description
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
(R)-3,3'-Di-9-phenanthrenyl-[1,1'-binaphthalene]-2,2'-diol (CAS 1058734-56-7), molecular formula C48H30O2 and molecular weight 638.75 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)-3,3'-Di-9-phenanthrenyl-[1,1'-binaphthalene]-2,2'-diol is typically pale yellow to yellow amorphous powder. Its solid-state physicochemical attributes — including a molecular weight of 638.75 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
