Storage and precautions:
The solid state is stored below 5℃, and the shelf life is 3 months; the heated and melted liquid state is stored at 44℃~46℃. If the storage time is prolonged, dimer insoluble substance will be generated, and its generation speed changes with temperature. The shelf life is 10 days under the protection of dry nitrogen, so it should be used up as soon as possible.
