Chemical Structure
Description
The molecular framework of 2-[Bis(1-methylethyl)phosphino]-1-[(11bS)-2,6-dimethyldinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-yl]-3-methyl-1H-indole (C37H37NO2P2) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, organophosphorus functionality, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
2-[Bis(1-methylethyl)phosphino]-1-[(11bS)-2,6-dimethyldinaphtho[2,1-d:1′,2′-f][1,3,2]dioxaphosphepin-4-yl]-3-methyl-1H-indole (CAS 952069-21-5), molecular formula C37H37NO2P2 and molecular weight 589.64 g/mol, is a CATO reference standard with documented purity and traceability.
