Diiodosilane (CAS 13760-02-6) is a compound that garners significant attention in specialized chemical sectors due to its unique properties and reactivity. As a silicon-based chemical intermediate, it plays a critical role in advanced synthesis and material science. Understanding its characteristics, how to handle it safely, and where to buy it from reputable sources are key considerations for any B2B purchaser or researcher in fields such as organic chemistry and semiconductor technology.

The chemical identity of Diiodosilane is defined by its molecular formula H2I2Si, and its CAS number is 13760-02-6. Physically, it is a colorless liquid. Key properties reported include a melting point of -1°C and a boiling point range of 56-60 °C at 25 mmHg, with a density of 2.834 g/mL at 25 °C. A critical characteristic is its high hydrolytic sensitivity; it reacts extremely rapidly with atmospheric moisture and can be pyrophoric. This necessitates strict handling procedures, typically within a glove box or a sealed system under an inert atmosphere, such as nitrogen. The compound may also be stabilized by metallic copper, and storage at refrigerated temperatures (2-8°C) away from light is recommended for long-term stability.

The applications of Diiodosilane are diverse and significant. In organic synthesis, it is utilized for cleaving ethers and converting alcohols into iodides, facilitating subsequent transformations. It also finds use in the synthesis of organometallic compounds and as a precursor in the deposition of silicon-containing thin films via ALD and CVD, particularly in the electronics industry. These applications demand a reliable supply of high-purity Diiodosilane, often exceeding 99%. For researchers and manufacturers, identifying a dependable supplier is paramount to ensure the success of their sensitive chemical processes.

When looking to purchase Diiodosilane, it is advisable to approach manufacturers and chemical suppliers that specialize in silanes and fine chemicals. Companies that can provide detailed technical data, safety information (SDS), and certificates of analysis (COA) are preferred. Exploring global markets, including reputable suppliers in China, can often provide access to high-quality Diiodosilane at competitive prices. Due diligence in selecting a supplier that prioritizes quality control and has a robust supply chain is key to a successful procurement experience. Negotiating purchase terms and understanding shipping requirements for hazardous materials are also important aspects.

In summary, Diiodosilane (CAS 13760-02-6) is a powerful and versatile chemical that requires careful handling and knowledgeable sourcing. By understanding its properties and prioritizing partnerships with reliable manufacturers, R&D professionals and procurement specialists can effectively integrate this vital silicon intermediate into their critical processes, driving innovation and achieving desired outcomes.
