Pentafluorophenyl 4-Nitrobenzenesulfonate what should I pay attention to when storing and transporting?

Pentafluorophenyl 4-nitrobenzenesulfonate is also an organic compound. When storing and transporting, many matters need to be paid attention to.
The first thing to pay attention to is its stability. The chemical properties of this compound may be more active, and it may decompose and deteriorate when exposed to heat, light or specific chemicals. Therefore, the storage place should be cool, dry and protected from light. If the temperature is too high, it may cause the chemical bonds in the molecule to break, triggering a decomposition reaction; light may also start a photochemical reaction, damaging its structure and properties.
