For B2B procurement professionals and R&D scientists, understanding the precise specifications of chemical raw materials is fundamental to successful product development and manufacturing. Methyltris(dimethylsiloxy)silane (CAS 17082-46-1) is a specialty silane compound with a growing presence in diverse industrial applications. As a leading manufacturer and supplier, we recognize the critical importance of detailed product specifications to ensure our clients can confidently buy and utilize this compound effectively. This guide breaks down the key specifications for Methyltris(dimethylsiloxy)silane, catering to the needs of industrial buyers.

Key Specifications for Methyltris(dimethylsiloxy)silane

When sourcing Methyltris(dimethylsiloxy)silane, several technical parameters are essential for evaluating its suitability for your specific application. These include:

  • Chemical Purity: The purity of Methyltris(dimethylsiloxy)silane is paramount. Typically, this compound is offered at a purity of 95% or 96% as determined by Gas Chromatography (GC). However, for highly sensitive applications in advanced materials or specialized formulations, higher purity grades might be required. As a dedicated manufacturer, we work to meet these stringent requirements.
  • CAS Number: 17082-46-1 is the unique identifier for Methyltris(dimethylsiloxy)silane, crucial for regulatory compliance and precise product identification in procurement and research.
  • Appearance: This compound is consistently described as a clear, colorless liquid. Any deviation from this appearance could indicate impurity or degradation, making it important to source from suppliers who maintain strict quality control.
  • Molecular Formula and Weight: The molecular formula is C7H24O3Si4, and its molecular weight is approximately 268.61 g/mol. These values are critical for stoichiometric calculations in synthesis and formulation.
  • Physical Properties: Key physical properties often listed include a boiling point (e.g., 164 °C at atmospheric pressure or 68 °C at 5 mm Hg), a melting point of -155 °C, a density around 0.861 g/mL, and a refractive index (e.g., n20/D 1.3852). These parameters are vital for handling, storage, and processing.
  • Flash Point: A flash point of approximately 103 °F (or 63°C as listed on some sources) is important for safety assessments and handling procedures.
