Description

Tungsten (VI) Isopropoxide, 5% w/v in Isopropanol is a specialized organometallic precursor solution, where tungsten is coordinated with isopropoxide ligands and stabilized in an isopropanol solvent. This product matters as a high-purity, ready-to-use source of tungsten for advanced materials synthesis, offering consistent reactivity and ease of handling compared to solid precursors. It is essential for researchers and manufacturers in the fields of catalysis, chemical vapor deposition (CVD), and sol-gel processing who require precise control over material properties.

Application

• Advanced Material Synthesis: A key precursor for the sol-gel production of tungsten oxide (WO3) thin films and nanoparticles used in smart windows, gas sensors, and electrochromic devices.
• Catalyst Development: Serves as a catalyst or catalyst precursor in organic synthesis and polymerization reactions, particularly for epoxidation and metathesis.
• Chemical Vapor Deposition (CVD) & Atomic Layer Deposition (ALD): Used to deposit high-purity tungsten or tungsten compound films onto substrates for semiconductor and microelectronic applications.
• Surface Modification & Coatings: Employed to create functional, wear-resistant, or catalytic coatings on various material surfaces.
• Research & Development: A vital reagent in academic and industrial R&D for exploring new tungsten-based materials and catalytic processes.

Quality Control

Our Tungsten (VI) Isopropoxide solution is produced and handled under stringent quality protocols to ensure batch-to-batch consistency and reliability for sensitive applications. Each lot is analyzed to confirm tungsten content, solvent purity, and the absence of critical metallic impurities. A comprehensive Certificate of Analysis (COA) detailing assay results, physical properties, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at room temperature (15-25°C) in a cool, dry, and well-ventilated area. Keep away from heat, sparks, open flames, and incompatible materials such as strong oxidizing agents. Due to its highly volatile and moisture-sensitive nature, containers must be kept sealed and allowed to equilibrate to room temperature before opening to prevent moisture ingress and pressure buildup.
