For professionals in the chemical and pharmaceutical industries, a thorough understanding of chemical intermediates is crucial for successful procurement and application. 1,2-Bis(trimethylsiloxy)ethane (CAS 7381-30-8), also known by synonyms like Ethylene glycol bis(trimethylsilyl ether) or trimethyl(2-trimethylsilyloxyethoxy)silane, is a compound that warrants detailed attention due to its role in various synthetic processes.

When you intend to buy 1,2-Bis(trimethylsiloxy)ethane, key properties will guide your selection. The compound typically presents as a clear, colorless to faint yellow liquid. This physical form is important for handling and processing in liquid-phase reactions. Its density is approximately 0.842 g/mL at 25 °C, and it has a refractive index (n20/D) around 1.403. These physical characteristics are consistent across reputable manufacturers and are often detailed in product specifications.

A critical specification for 1,2-Bis(trimethylsiloxy)ethane is its purity. While various grades may exist, a common and highly sought-after purity level is 95% or higher, often determined by Gas Chromatography (GC). Higher purity is essential for applications where trace impurities could negatively affect reaction yields or the final product's performance. When searching for a supplier, always confirm the purity level and the analytical methods used for its determination.

The boiling point of 1,2-Bis(trimethylsiloxy)ethane is typically in the range of 165-166 °C at atmospheric pressure. This relatively moderate boiling point influences its use in distillation and reaction conditions. Safety data sheets (SDS) will also provide crucial information regarding its flash point (around 115 °F), suggesting it is a flammable liquid and requires appropriate handling and storage precautions. Understanding these properties is vital for safe laboratory and industrial use.

For procurement managers, understanding these specifications allows for more informed decision-making when comparing offers and negotiating a price. A reliable manufacturer or supplier will readily provide detailed technical data sheets and safety information for their product. Whether you are looking to purchase small research quantities or bulk industrial volumes of CAS 7381-30-8, clarity on these properties ensures you are acquiring the right material for your specific needs.

In summary, familiarizing yourself with the appearance, density, refractive index, purity, boiling point, and safety profile of 1,2-Bis(trimethylsiloxy)ethane is fundamental. This knowledge empowers buyers to effectively engage with suppliers, ensure product quality, and ultimately achieve successful outcomes in their chemical endeavors.
