Description

Hexamethyl-D18-Disilane is a deuterated organosilicon compound, specifically the perdeuterated analog of hexamethyldisilane. This high-purity isotopically labeled material is critical for applications requiring minimal interference from proton signals, offering enhanced spectral clarity and stability. It is primarily utilized in advanced research and development within the fields of nuclear magnetic resonance (NMR) spectroscopy, organic synthesis, and materials science, serving as a valuable reagent, internal standard, or precursor for deuterated silicon-containing molecules.

Application

• Internal standard or reference compound in Nuclear Magnetic Resonance (NMR) spectroscopy, particularly for silicon-29 (29Si) studies.
• Deuterium-labeled precursor in the synthesis of specialized organosilicon compounds for research and development.
• Key reagent in mechanistic studies and isotopic labeling experiments in organic and organometallic chemistry.
• Starting material for the preparation of deuterated silylating agents used in analytical chemistry.
• Used in the development of advanced materials, such as deuterated polymers or silicon-based thin films for electronics and optics.
• Essential for academic and industrial R&D where isotopic purity and chemical stability are paramount.

Quality Control

Our Hexamethyl-D18-Disilane is produced and handled under stringent conditions to ensure the highest isotopic and chemical purity for research applications. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing key parameters such as isotopic enrichment (D-atom %), chemical purity, and identity confirmation. We adhere to rigorous internal quality standards to guarantee batch-to-batch consistency and reliability for your critical R&D work.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., argon or nitrogen) to prevent degradation. Keep away from strong oxidizing agents.
