Product Overview
Hexamethyldisiloxane (HMDSO) 99% is a high-purity organosilicon compound widely used in laboratory synthesis due to its excellent volatility and moisture-scavenging properties. This colorless liquid features a low boiling point, making it an efficient solvent and reagent in silylation reactions, where it replaces active hydrogen atoms with trimethylsilyl groups. Its hydrophobic nature ensures minimal water interference, enhancing reaction purity. The synthesis-grade quality guarantees minimal impurities, ensuring reliable and reproducible results in sensitive applications. HMDSO is also valued for its role in surface modification and as a precursor in chemical vapor deposition (CVD) processes. Stored under inert conditions, it maintains stability over extended periods, making it a dependable choice for research and development workflows.
FAQs
1. What is the boiling point of hexamethyldisiloxane 99%?
The boiling point of hexamethyldisiloxane is approximately 101°C, making it highly volatile and suitable for quick evaporation in lab processes.
2. Can this product be used for gas chromatography?
Yes, hexamethyldisiloxane 99% is often employed as a solvent or derivatization agent in gas chromatography due to its clean baseline and compatibility with most stationary phases.
3. How should hexamethyldisiloxane be stored to maintain purity?
Store in a tightly sealed container under dry, inert conditions (e.g., nitrogen or argon) to prevent moisture absorption and oxidation. Keep away from heat and ignition sources.
4. Is this product compatible with glassware and standard lab equipment?
Hexamethyldisiloxane is generally compatible with glass and most common lab materials like PTFE or stainless steel, but avoid prolonged contact with strong oxidizing agents.
5. What are the key safety precautions when handling hexamethyldisiloxane?
Use in a well-ventilated fume hood, wear protective gloves and goggles, and avoid inhalation or skin contact. It is flammable, so keep away from open flames and sparks.
