Description

Tris(Cyclopentadienyl)Gadolinium CAS NO 1272-21-5 is an organometallic compound of gadolinium, a rare earth metal, featuring three cyclopentadienyl ligands. This compound is a critical precursor in advanced materials science, particularly valued for its role in depositing gadolinium-containing thin films. It is essential for researchers and manufacturers in the semiconductor and specialty chemical industries who require high-purity metal-organic sources for chemical vapor deposition (CVD) and atomic layer deposition (ALD) processes.

Application

• Chemical Vapor Deposition (CVD) Precursor: Serves as a high-purity gadolinium source for depositing gadolinium oxide (Gd₂O₃) and other gadolinium-based thin films on semiconductor wafers.
• Atomic Layer Deposition (ALD): Used in the precise, layer-by-layer growth of rare earth oxide films for advanced gate dielectrics and memory devices.
• Specialty Catalysis: Acts as a catalyst or catalyst component in specialized organic synthesis and polymerization reactions due to its unique Lewis acidity.
• Research & Development: A key starting material in academic and industrial R&D for exploring new magnetic materials, luminescent compounds, and other functional materials based on rare earth elements.
• Doping Agent: Employed to introduce gadolinium ions into host matrices (e.g., glasses, ceramics) to modify optical, magnetic, or electrical properties.
• Production of Organolanthanide Complexes: Used as a synthon for preparing more complex gadolinium organometallic compounds with tailored properties.

Quality Control

Our Tris(Cyclopentadienyl)Gadolinium is produced and handled under stringent quality management protocols to ensure batch-to-batch consistency and high purity, essential for sensitive deposition processes. Each lot is analyzed to confirm identity, purity, and the absence of critical metallic impurities. A comprehensive Certificate of Analysis (COA) detailing specific test results is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Due to its highly reactive nature, this material must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry place. It is both hygroscopic (moisture-sensitive) and easily oxidized. Recommended long-term storage temperature is 2-8°C. The container must be kept sealed and only opened in a controlled, moisture-free environment.
