n-(2'-(Diphenylphosphanyl)-[1,1'-binaphthalen]-2-yl)methanesulfonamide CAS 278800-87-6

Description

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.

CATO supplies n-(2'-(Diphenylphosphanyl)-[1,1'-binaphthalen]-2-yl)methanesulfonamide (CAS 278800-87-6), a certified reference material (molecular formula C33H26NO2PS, MW 531.60 g/mol) for analytical method development and quality control.

n-(2'-(Diphenylphosphanyl)-[1,1'-binaphthalen]-2-yl)methanesulfonamide (C33H26NO2PS) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, organophosphorus functionality, a hydroxyl group, an ether linkage. 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).

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.
