Chemical Structure

(11bS)-2,6-diiodo-N,N-bis((S)-1-phenylethyl)dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-amine CAS 1642865-16-4 chemical structure

Description

Compared with other compounds in its class, the molecular weight of 823.46 g/mol gives (11bS)-2,6-diiodo-N,N-bis((S)-1-phenylethyl)dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-amine distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

(11bS)-2,6-diiodo-N,N-bis((S)-1-phenylethyl)dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-amine (CAS 1642865-16-4), molecular formula C36H28I2NO2PS and molecular weight 823.46 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of (11bS)-2,6-diiodo-N,N-bis((S)-1-phenylethyl)dinaphtho[2,1-d:1',2'-f][1,3,2]dioxaphosphepin-4-amine (C36H28I2NO2PS) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, organophosphorus functionality, a hydroxyl group, an ether linkage, iodine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

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.
