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.
CATO supplies (11bR,11'bR)-4,4'-(Oxybis(2,1-phenylene))didinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepine (CAS 391860-55-2), a certified reference material (molecular formula C52H84O5P2, MW 851.17 g/mol) for analytical method development and quality control.
The molecular framework of (11bR,11'bR)-4,4'-(Oxybis(2,1-phenylene))didinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepine (C52H84O5P2) is characterized by a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
