English description(英文原文,共 950 字符)
Product Name:1,4-Bis(diphenylphosphino)butane
English Name:1,4-Bis(diphenylphosphino)butane
CAS No.:7688-25-7
Aliases:dppb, tetramethylenebis(diphenylphosphine)
Molecular Formula:C28H28P2
Physical Properties:White crystalline solid, melting point 136-141°C, insoluble in water, soluble in most organic solvents such as chloroform, ether, and benzene. Stable in air, but should be stored sealed and protected from light.
Uses:Used as a bidentate phosphine ligand in transition metal-catalyzed reactions, widely applied in palladium-catalyzed coupling reactions, rhodium-catalyzed hydroformylation, and asymmetric synthesis. This ligand effectively stabilizes metal centers and enhances catalytic activity and selectivity.
Technical Specifications:
Melting point: 136-141°C
Assay: ≥98.0% (HPLC)
Appearance: white to off-white crystalline powder
Loss on drying: ≤0.5%
Solubility: soluble in chloroform, ether, and benzene; insoluble in water
