After synthesis, a variety of separation techniques are also used to obtain high-purity target products.

1-Methyl-1H-imidazole-4-carboxylate is a very important chemical substance, and many key points need to be paid attention to during storage and transportation.
Bear the brunt, and be sure to ensure that the environment is dry when storing. This substance is susceptible to moisture. If the environment is humid, it may cause chemical reactions such as hydrolysis, which will damage its chemical properties and purity. Therefore, it should be stored in a dry and well-ventilated place, preferably in a sealed container to prevent moisture from invading.
Secondly, the temperature should not be ignored. It should be stored in a suitable temperature range to avoid high or low temperatures. If the temperature is too high, or accelerates its chemical reaction rate, causing it to deteriorate; if the temperature is too low, in some cases, it may cause its crystallization to precipitate, which will affect subsequent use. Generally speaking, it is more suitable to store at room temperature, but please refer to relevant information or product instructions for details.
Furthermore, the storage place should be away from fire sources and oxidants. This substance is flammable to a certain extent, and it is easy to cause fire in case of fire sources; and contact with oxidants, or violent reactions occur, endangering safety.
As for transportation, the packaging must be solid and reliable. Appropriate packaging materials should be selected to resist vibration and collision during transportation, and to prevent material leakage due to package damage.
During transportation, environmental conditions should also be strictly controlled. Keep the transportation environment dry and suitable temperature, and follow relevant transportation regulations and standards.
