Description

Diphosphane CAS NO 13445-50-6 is an inorganic compound consisting of a phosphorus-phosphorus single bond, representing a fundamental building block in phosphorus chemistry. Its high reactivity makes it a valuable precursor for synthesizing complex organophosphorus compounds, phosphorus-containing polymers, and specialized ligands for catalysis. This chemical is essential for research and development laboratories, specialty chemical manufacturers, and industries focused on advanced materials, flame retardants, and agrochemical intermediates.

Application

• Chemical Synthesis Precursor: Acts as a key starting material for the production of organophosphines, phosphine oxides, and other functionalized phosphorus derivatives.
• Ligand and Catalyst Development: Used in the preparation of novel bidentate and multidentate phosphorus ligands for homogeneous catalysis in fine chemical and pharmaceutical manufacturing.
• Polymer and Material Science: Serves as a monomer or cross-linking agent in the development of phosphorus-containing polymers with potential flame-retardant or electronic properties.
• Agrochemical Intermediates: Employed in the synthesis of advanced pesticide and herbicide active ingredients.
• Semiconductor and Electronics: Investigated for use in chemical vapor deposition (CVD) processes for doping or depositing thin films containing phosphorus.
• Research and Development: A critical reagent in academic and industrial R&D for exploring new reaction pathways and phosphorus-based molecules.

Quality Control

Our Diphosphane is produced and handled under stringent quality protocols to ensure batch-to-batch consistency and purity. We employ advanced analytical techniques, including gas chromatography (GC) and NMR spectroscopy, to verify identity and assay. A comprehensive Certificate of Analysis (COA) detailing purity, impurity profile, and physical properties 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 (e.g., nitrogen or argon) at recommended temperatures between 2°C and 8°C. The storage area should be cool, dry, and well-ventilated, away from sources of ignition, heat, and oxidizing agents.
