2-Fluorobenzylhydrazine Dihydrochloride needs to pay attention to when storing and transporting

When storing and transporting 2-fluorobenzylhydrazine dihydrochloride, pay attention to the following matters.

This compound is chemically active, and the storage place must be dry, because moisture is easy to cause its chemical reaction to cause deterioration. Humidity should be controlled within a specific range, away from water sources and high humidity environments, such as basements or places without dehumidification equipment.

Temperature is also critical. It should be stored in a suitable low temperature environment to avoid high temperature, because high temperature will accelerate decomposition or cause other adverse reactions. Generally speaking, follow the recommended temperature of the product instructions, usually 2-8 ° C refrigeration or lower freezing temperature.

When transporting, ensure that the packaging is tight. Use packaging materials with good sealing and protective properties to prevent leakage and contact with external substances. The outer packaging needs to be sturdy, and the buffer material is sufficient to reduce the impact of vibration and collision during transportation.
