Chemical Structure
Description
2-[Bis[3,5-bis(1,1-dimethylethyl)phenyl]phosphino]benzoic acid (CAS 2407524-76-7), molecular formula C35H47O2P and molecular weight 530.72 g/mol, is a CATO reference standard with documented purity and traceability.
2-[Bis[3,5-bis(1,1-dimethylethyl)phenyl]phosphino]benzoic acid (C35H47O2P) 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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.
