Trimethylsilyl trifluoromethanesulfonate (TMSOTf) is a powerful and highly reactive chemical reagent. As a leading supplier of specialty chemicals, NINGBO INNO PHARMCHEM CO.,LTD. understands the importance of not only providing high-quality products but also ensuring that our customers have the knowledge to handle them safely and effectively. For procurement managers and laboratory scientists alike, understanding the properties and proper handling of TMSOTf is crucial for successful and safe application. If you are considering to buy trimethylsilyl trifluoromethanesulfonate, this information is vital.

Key Properties of TMSOTf

TMSOTf is characterized by its high electrophilicity and sensitivity to moisture. It is typically a colorless to light yellow, fuming liquid with a distinct odor. Its molecular formula is C4H9F3O3SSi, and it has a molecular weight of approximately 222.26 g/mol. Key physical properties include a boiling point of around 77 °C at 80 mmHg and a density of approximately 1.228 g/mL at 25 °C. Its refractive index is typically around 1.36.

Reactivity and Hazards

Due to its moisture sensitivity, TMSOTf reacts rapidly with water and protic solvents, often releasing corrosive fumes. This hydrolytic sensitivity necessitates careful handling under anhydrous conditions, typically in a dry inert atmosphere such as nitrogen or argon. Its classification as a corrosive and flammable liquid (UN Number: UN2920) means it requires appropriate safety precautions during transport, storage, and use. Hazard statements commonly associated with TMSOTf include H226 (Flammable liquid and vapor) and H314 (Causes severe skin burns and eye damage).

Safe Handling and Storage Recommendations

For safe handling, it is imperative to use appropriate personal protective equipment (PPE), including chemical-resistant gloves, safety goggles, and a face shield. All operations involving TMSOTf should be conducted in a well-ventilated fume hood. Storage should be in a cool, dry, and well-ventilated area, with containers kept tightly closed to prevent moisture ingress. It should be stored away from incompatible materials, such as water, alcohols, and strong oxidizing agents. When purchasing from a reputable manufacturer like us, you can be assured of receiving product with appropriate packaging and labeling that adheres to safety regulations.
