Description

N,n-Bis[(Diphenylphosphino)Methyl]-3-(Triethoxysilyl)Propylamine is a sophisticated bifunctional organosilane ligand that combines a phosphine donor site with a hydrolyzable triethoxysilyl group. This unique molecular architecture is critical for creating advanced hybrid materials and catalysts with enhanced stability and performance. It is an essential precursor for researchers and manufacturers in the fields of heterogeneous catalysis, surface modification, and material science, where precise molecular anchoring and tailored reactivity are required.

Application

• Heterogeneous Catalyst Synthesis: As a ligand for immobilizing transition metal complexes (e.g., Pd, Pt, Rh) onto silica, metal oxides, or polymer supports for recyclable catalytic systems.
• Surface Functionalization Agent: For modifying glass, silicon, or metal surfaces to introduce phosphine sites for subsequent metal binding or to alter surface properties.
• Advanced Material Precursor: In the development of organic-inorganic hybrid materials, mesoporous silicas, and functional coatings with integrated catalytic or sensing capabilities.
• Cross-Coupling Catalysis: As a component in ligand systems for Heck, Suzuki, Sonogashira, and other C-C bond-forming reactions, especially where catalyst recovery is desired.
• Hydrogenation & Hydrosilylation Catalysts: For creating supported catalysts used in selective hydrogenation or hydrosilylation processes.
• Research & Development: A valuable building block in academic and industrial R&D for exploring new catalytic cycles and material interfaces.

Quality Control

Every batch of N,n-Bis[(Diphenylphosphino)Methyl]-3-(Triethoxysilyl)Propylamine is produced and controlled under strict quality management systems. We employ advanced analytical techniques including NMR (¹H, ³¹P, ¹³C), HPLC, and FTIR to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with each shipment to support your quality assurance and R&D documentation.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. Due to its sensitivity to oxidation and moisture, containers should be flushed with inert gas after each opening to maintain product integrity.
