Chemical Structure
Description
The molecular framework of (R)-(-)-4-Chlorodinaphthol[2,1-d:1',2'-f][1,3,2]dioxaphosphepin 155613-52-8 (R)-(-)-1,1'-BINAPHTHYL-2,2'-DIOXYCHLOROPHOSPHINE;(R)-(-)-4-CHLORODINAPHTHOL[2,1-D:1',2'-F][1,3,2]DIOXAPHOSPHEPIN;(R)-(-)-CHLORODINAPHTHOL[2,1-D:1',2'-F][1,3,2]DIOXAPHOSPHEPIN;(R)-(1,1'-BINAPHTHALENE-2,2'-DIOXY)CHLOROPHOSPHINE;(R)-1,1'-BINAPHTHYL-2,2'-DIYL PHOSPHOROCHLORIDATE;(S)-(+)-1,1'-BINAPHTHYL-2,2'-DIOXYCHLOROPHOSPHINE;(S)-(+)-4-CHLORODINAPHTHOL[2,1-D:1',2'-F][1,3,2]DIOXAPHOSPHEPIN;(S)-(+)-CHLORODINAPHTHOL[2,1-D:1',2'-F][1,3,2]DIOXAPHOSPHEPIN;(S)-1,1'-BINAPHTHYL-2,2'-DIYL PHOSPHOROCHLORIDATE SC11529 (C20H12ClO2P) is characterized by a steroid core, organophosphorus functionality, a hydroxyl group, an ether linkage, chlorine 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. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
