Chemical Structure
Description
3,3'-Bis(3,5-diisopropylphenyl)-1,1'-binapthyl-2,2'-diyl hydrogenphosphate (C44H45O4P) contains a phosphate ester group, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO supplies 3,3'-Bis(3,5-diisopropylphenyl)-1,1'-binapthyl-2,2'-diyl hydrogenphosphate (CAS 1706459-35-9), a certified reference material (molecular formula C44H45O4P, MW 668.80 g/mol) for analytical method development and quality control.
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.
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.
