Finally, after multiple reactions and treatments, the final product is separated, purified and identified to ensure that it is the desired (2S) -1,2,3,4-tetrahydro-3-isobenzofuranoyl benzoic anhydride, and to achieve the required purity and Quality Standards. The entire synthesis process requires chemical principles, fine operation, and careful control of the details of each reaction to successfully obtain the target product.

(S) -1,2,3,4-tetrahydro-3-isopentenyl cinnamic acid lactone needs to pay attention to many key matters during storage and transportation.
First, this material is quite sensitive to environmental conditions. In terms of temperature, it should be stored in a cool place, and must not be placed in a high temperature place to avoid decomposition or deterioration due to excessive temperature. Due to high temperature, it is easy to change the molecular structure, which in turn affects its chemical properties and quality. Similarly, humidity needs to be strictly controlled. Humid environments may cause deliquescence and other conditions, resulting in impaired purity. Therefore, the storage place must be kept dry.
Second, the packaging must be strong and well sealed during transportation. This is to prevent external factors from interfering, such as oxygen and moisture in the air coming into contact with it, triggering chemical reactions such as oxidation. In addition, it is necessary to avoid mixing with other chemicals to prevent unpredictable reactions. Due to its unique chemical structure, certain chemicals may interact with them, causing product failure and even danger.
Third, whether it is storage or transportation, it must strictly follow relevant regulations and safety standards. Operators need to be professionally trained and familiar with their characteristics and latent risks, so that they can take appropriate protective measures during operation to ensure their own safety and avoid adverse effects on the product. In conclusion, the storage and transportation of (S) -1,2,3,4-tetrahydro-3-isopentenyl cinnamic acid lactone requires great care and attention to every detail to ensure its quality and safety.
