Description

Tetraethylgermane CAS NO 597-63-7 is a high-purity organogermanium compound characterized by its four ethyl groups bonded to a central germanium atom. This compound serves as a critical precursor in advanced materials science and semiconductor research, enabling the controlled deposition of germanium-containing thin films. It is primarily utilized by manufacturers and R&D laboratories in the electronics, photovoltaics, and specialty chemical synthesis sectors.

Application

• Chemical Vapor Deposition (CVD) and Atomic Layer Deposition (ALD): A key precursor for depositing high-purity germanium or germanium-doped films in semiconductor and microelectronic device fabrication.
• Advanced Material Synthesis: Used as a building block for synthesizing novel organogermanium polymers, catalysts, and other functional materials.
• Research & Development: Essential for academic and industrial research exploring new germanium-based chemistry, including catalysis and material properties.
• Optoelectronics and Photovoltaics: Potential application in the development of next-generation solar cells and optoelectronic components where germanium films are required.
• Specialty Organic Synthesis: Acts as an ethylating agent or intermediate in the synthesis of complex organometallic compounds for specialized applications.

Quality Control

Our Tetraethylgermane is produced and handled under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including Gas Chromatography (GC) and NMR spectroscopy, to ensure high chemical purity and identity. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are provided with every shipment to guarantee traceability and compliance with your technical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, well-ventilated area. Due to its sensitivity to oxidation, the container should be kept sealed under positive pressure of inert gas when not in use. Recommended long-term storage temperature is 2-8°C.
