(1S,1'S,2S,2'S)-2,2'-Di-tert-butyl-2,2',3,3'-tetrahydro-1H,1'H-[1,1'-biisophosphindole] 2,2'-dioxide CAS 795289-52-0 chemical structure

Description

The occurrence of (1S,1'S,2S,2'S)-2,2'-Di-tert-butyl-2,2',3,3'-tetrahydro-1H,1'H-[1,1'-biisophosphindole] 2,2'-dioxide is closely related to a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies (1S,1'S,2S,2'S)-2,2'-Di-tert-butyl-2,2',3,3'-tetrahydro-1H,1'H-[1,1'-biisophosphindole] 2,2'-dioxide (CAS 795289-52-0), a certified reference material (molecular formula C24H32O2P2, MW 414.46 g/mol) for analytical method development and quality control.

Based on its molecular formula C24H32O2P2, (1S,1'S,2S,2'S)-2,2'-Di-tert-butyl-2,2',3,3'-tetrahydro-1H,1'H-[1,1'-biisophosphindole] 2,2'-dioxide contains a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 414.46 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
