Description

Tris(Ethylcyclopentadienyl)Lanthanum (III), 98% (99.9%-La) (Reo) is a highly pure organolanthanum compound, specifically a lanthanocene, used as a specialized precursor in advanced materials synthesis. This product is critical for applications requiring high-purity lanthanum sources with defined organic ligands for precise deposition and doping processes. It is primarily utilized by R&D and production teams in the semiconductor, catalysis, and specialty chemical manufacturing industries.

Application

• Chemical Vapor Deposition (CVD) & Atomic Layer Deposition (ALD): Serves as a high-purity precursor for depositing lanthanum-containing thin films in semiconductor fabrication, particularly for high-k dielectric layers.
• Polymerization Catalysis: Acts as a catalyst or co-catalyst component in the synthesis of specialized polymers, where it can influence stereochemistry and polymer chain growth.
• Organic Synthesis & Organometallic Chemistry: Used as a reagent in research-scale organic transformations, including cyclization and coupling reactions, leveraging the unique reactivity of lanthanide metals.
• Dopant Source for Materials Science: Employed to dope lanthanum into ceramic, glass, or phosphor matrices to modify electrical, optical, or magnetic properties.
• Production of Specialty Catalysts: A key starting material for manufacturing heterogeneous and homogeneous catalysts used in fine chemical and petrochemical processes.

Quality Control

Every batch of Tris(Ethylcyclopentadienyl)Lanthanum (III) is produced and tested under stringent quality management protocols to ensure batch-to-batch consistency and high purity. Our products undergo rigorous quality testing, including spectroscopic and elemental analysis, to ensure compliance with industry standards. Certificates of Analysis (COA) detailing purity, metal content, and impurity profiles are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Due to its hygroscopic (moisture-sensitive) and easily oxidized nature, this material must be stored under an inert atmosphere (argon or nitrogen) in a cool, dry place. Recommended storage temperature is 2-8°C for long-term stability. The container should be kept tightly sealed in a dry inert atmosphere glovebox or desiccator when not in use.
