Chemical Structure

1,2:5,6-Di-O-isopropylidene-3,4-bis[(R)-1,1'-binaphthyl-2,2'-diyl]phosphite-D-mannitol CAS 1272671-11-0 chemical structure

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 1,2:5,6-Di-O-isopropylidene-3,4-bis[(R)-1,1'-binaphthyl-2,2'-diyl]phosphite-D-mannitol (CAS 1272671-11-0), a certified reference material (molecular formula C52H44O10P2, MW 890.85 g/mol) for analytical method development and quality control.

1,2:5,6-Di-O-isopropylidene-3,4-bis[(R)-1,1'-binaphthyl-2,2'-diyl]phosphite-D-mannitol (C52H44O10P2) contains a phosphate ester group, a carboxylic acid group, a hydroxyl group, an ether linkage, a polycyclic aromatic system. 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.
