Description

Tetraethoxy-D20-Silane is a deuterated organosilicon compound, specifically the perdeuterated analogue of tetraethoxysilane (TEOS). This high-purity isotopically labeled material is critical for applications requiring minimal interference from proton signals and enhanced stability. It is primarily utilized in advanced research and development within the semiconductor, pharmaceutical, and analytical chemistry sectors. The compound serves as a specialized precursor for creating deuterated silica-based materials and as a reagent in mechanistic studies.

Application

• NMR Spectroscopy & Analytical Standards: Used as an internal standard or chemical shift reference in deuterium NMR and other spectroscopic techniques due to its defined isotopic purity.
• Deuterated Material Synthesis: Acts as a key precursor for sol-gel processes to produce deuterium-labeled silicon dioxide (SiO2) films, coatings, and monoliths for specialized optical and electronic applications.
• Semiconductor Manufacturing: Employed in the chemical vapor deposition (CVD) of low-proton-content silicate glass layers in microelectronics, where hydrogen contamination must be minimized.
• Isotope Labeling Studies: Essential reagent in pharmaceutical and chemical research for tracing reaction pathways, studying kinetics, and elucidating mechanisms using deuterium as a stable isotopic tracer.
• Specialty Polymers & Coatings: Used in formulating high-performance, deuterated hybrid organic-inorganic polymers for research in photonics and surface science.

Quality Control

Our Tetraethoxy-D20-Silane is manufactured under controlled conditions to ensure exceptional isotopic and chemical purity, meeting the stringent requirements of research and high-tech industries. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing key parameters such as isotopic enrichment (D-atom %), chemical purity, and impurity profiles. We adhere to rigorous internal quality standards to guarantee batch-to-batch consistency and reliability for your critical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent hydrolysis. Keep away from heat, sparks, and open flames.
