1,3-Di-n-octyltetramethyldisiloxane is a siloxane with two n-octyl groups, offering a balance of organic and inorganic character. Its physical properties are crucial for its application: it presents as a clear liquid with a density of 0.891 g/mL and a boiling point of 122-125 °C at 0.2 mm Hg. The molecular formula is C20H46OSi2, and its purity typically exceeds 95%, making it suitable for demanding industrial uses. The flash point of over 110 °C signifies a degree of safety in handling and processing, which is a key consideration for chemical manufacturers.

The dual nature of siloxanes, with their stable silicon-oxygen backbone and customizable organic side groups, makes them highly versatile. In the case of 1,3-Di-n-octyltetramethyldisiloxane, the long octyl chains contribute to increased hydrophobicity and reduced surface tension compared to shorter-chain siloxanes. This makes it an excellent candidate for applications requiring water repellency, lubrication, or improved spreadability. Industrial chemists might consider this compound for formulating advanced lubricants, specialty greases, or as a component in silicone-based release agents. Its compatibility with various organic solvents also facilitates its incorporation into diverse formulations.

Furthermore, this siloxane can serve as a valuable intermediate in the synthesis of more complex silicone polymers and resins. By reacting its siloxy groups, chemists can create cross-linked networks or introduce specific functionalities tailored for particular end-use applications. For instance, it could be employed in the development of silicone surfactants, emulsifiers, or as an additive to enhance the flexibility and impact resistance of plastics and coatings. The consistent quality and availability from a reliable manufacturer are key when integrating such specialized intermediates into manufacturing processes.
