Precautions

  1. This reagent is extremely sensitive to moisture, which can easily lead to its decomposition and inactivation. Therefore, the operating environment must be kept completely dry.

  2. Prolonged exposure to air may cause a decrease in the reactivity of the reagent; it is recommended to transfer and use it under the protection of an inert gas.

  3. It should be sealed and stored in a cool, dry environment to avoid high temperatures that could cause solvent evaporation or increase the risk of reaction.

  4. Because it readily reacts violently with acids and substances containing active hydrogen, it must be stored in strictly separate areas.

  5. Protective gloves, safety glasses, and lab coats must be worn during operation to prevent reagents from coming into contact with the skin and eyes.

  6. If accidentally contacted, rinse immediately with plenty of water and seek medical attention promptly.
