Description

Selenium Tetrachloride is a versatile and highly reactive inorganic compound primarily used as a precursor in chemical synthesis. Its strong Lewis acid character makes it a critical reagent for introducing selenium into organic molecules and for the production of other selenium compounds. This material is essential for research and development laboratories, specialty chemical manufacturers, and industries involved in advanced material science and catalysis.

Application

• Chemical Synthesis: A key precursor for the preparation of other selenium compounds, including organoselenium reagents and selenium dioxide.
• Catalyst Production: Used in the formulation of specialized catalysts for organic transformations and polymerization reactions.
• Semiconductor Research: Serves as a selenium source in the chemical vapor deposition (CVD) of thin-film semiconductors and photovoltaic materials.
• Organic Intermediate: Employed in the synthesis of selenium-containing pharmaceuticals, agrochemicals, and fine chemicals.
• Laboratory Reagent: Utilized as a strong chlorinating and oxidizing agent in research-scale inorganic and organic chemistry.
• Glass & Pigment Manufacturing: Acts as an intermediate in processes for producing selenium-based colorants and decolorizing agents for glass.

Quality Control

Our Selenium Tetrachloride is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. We provide comprehensive Certificates of Analysis (COA) detailing key parameters such as assay, impurity profiles, and physical properties. Our quality management system is designed to meet the stringent requirements of research and industrial applications, ensuring reliable performance in your processes.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from incompatible materials. Due to its hygroscopic and strong acid/organic solvent nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition. Recommended storage temperature is 2-8°C for long-term stability.
