Description

Bis(Cyclopentadienyl)Tungsten Dichloride is a versatile organometallic compound, also known as Tungstenocene dichloride, that serves as a critical precursor in advanced materials synthesis and catalysis. Its value lies in its ability to introduce tungsten into complex molecular frameworks, enabling the development of novel materials with unique electronic and structural properties. This high-purity chemical is essential for researchers and manufacturers in the fields of organometallic chemistry, chemical vapor deposition (CVD), and specialty polymer catalysis.

Application

• Catalyst Precursor: Serves as a starting material for synthesizing homogeneous and heterogeneous catalysts for olefin polymerization and other organic transformations.
• Chemical Vapor Deposition (CVD): Used as a volatile tungsten source for depositing thin films of tungsten, tungsten carbide, or tungsten nitride on substrates for semiconductor and coating applications.
• Organometallic Synthesis: A key reagent for the preparation of other tungstenocene derivatives and complexes used in academic and industrial research.
• Material Science Research: Employed in the development of new inorganic-organic hybrid materials and metal-organic frameworks (MOFs) with tailored properties.
• Polymerization Initiator: Acts as a component in catalyst systems for the ring-opening metathesis polymerization (ROMP) of cyclic olefins.

Quality Control

Our Bis(Cyclopentadienyl)Tungsten Dichloride is manufactured under controlled conditions to ensure batch-to-batch consistency and high purity. Each lot undergoes rigorous analytical testing, including NMR, elemental analysis (CHN), and XRD for structural confirmation and purity verification. Certificates of Analysis (COA) detailing all specifications are provided with every shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, it is recommended to handle and store the material under an inert atmosphere (argon or nitrogen) to prevent decomposition. Ideal storage temperature is between 2°C and 8°C for long-term stability.
