Description

Di-T-Butylmethylphosphine is a highly reactive tertiary phosphine ligand, a key building block in advanced organometallic chemistry and catalysis. Its sterically demanding structure makes it exceptionally valuable for creating highly active and selective transition metal catalysts. This compound is primarily sought by R&D chemists and process engineers in the pharmaceutical, agrochemical, and fine chemical industries for applications in cross-coupling reactions, hydrogenation, and hydroformylation.

Application

• Catalyst Ligand for Cross-Coupling Reactions: Essential component in Buchwald-Hartwig amination, Suzuki-Miyaura, and Negishi couplings for pharmaceutical intermediate synthesis.
• Hydrogenation Catalyst Precursor: Used to formulate highly active catalysts for the selective reduction of complex organic molecules.
• Hydroformylation Catalysis: Employed in the development of rhodium and cobalt-based catalysts for the production of aldehydes from olefins.
• Polymerization Catalyst Systems: Serves as a ligand in late-transition metal catalysts for olefin polymerization and copolymerization.
• Organic Synthesis Reagent: Acts as a nucleophilic phosphine source in the synthesis of novel phosphonium salts and other organophosphorus compounds.
• Material Science Research: Used in the development of novel metal-organic frameworks (MOFs) and catalytic materials.

Quality Control

Our Di-T-Butylmethylphosphine is manufactured under strict quality protocols to ensure batch-to-batch consistency and high purity, critical for sensitive catalytic applications. Each lot is analyzed via NMR, GC, and titration to confirm identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, moisture content, and other critical parameters is provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly volatile and easily oxidized nature, this material must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated area. Recommended storage temperature is 2-8°C for long-term stability. Keep away from heat, sparks, open flames, and strong oxidizing agents.
