Chemical Structure

(4S,4'S)-2,2'-(((3,5-Di-tert-butyl-4-methoxyphenyl)phosphinediyl)bis(2,1-phenylene))bis(4-(tert-butyl)-4,5-dihydrooxazole) CAS 2583673-76-9 chemical structure

Description

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

CATO supplies (4S,4'S)-2,2'-(((3,5-Di-tert-butyl-4-methoxyphenyl)phosphinediyl)bis(2,1-phenylene))bis(4-(tert-butyl)-4,5-dihydrooxazole) (CAS 2583673-76-9), a certified reference material (molecular formula C41H55N2O3P, MW 654.86 g/mol) for analytical method development and quality control.

The molecular framework of (4S,4'S)-2,2'-(((3,5-Di-tert-butyl-4-methoxyphenyl)phosphinediyl)bis(2,1-phenylene))bis(4-(tert-butyl)-4,5-dihydrooxazole) (C41H55N2O3P) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a phosphonate group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
