Chemical Structure
Description
The occurrence of 2’-[2-Biphenylyl(hydroxy)methyl]-2-hydroxy-3-(diphenylphosphino)-[1,1’-binaphthalene] is closely related to organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 2’-[2-Biphenylyl(hydroxy)methyl]-2-hydroxy-3-(diphenylphosphino)-[1,1’-binaphthalene] (CAS 1661883-77-7), a certified reference material (molecular formula C45H33O2P, MW 636.72 g/mol) for analytical method development and quality control.
2’-[2-Biphenylyl(hydroxy)methyl]-2-hydroxy-3-(diphenylphosphino)-[1,1’-binaphthalene] (C45H33O2P) contains organophosphorus functionality, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
