Frequently Asked Question

Questions asked by users might not always be phrased in the clearest way.

Should i store my anhydride in pyridine product, in a refridgerator or is roomtemperature good enough?

Accepted Answer

Anhydrides are generally moisture-sensitive and can react with water to form carboxylic acids. Therefore, it's crucial to store them in a dry environment. While a refrigerator can provide a cool and stable environment, the humidity inside a refrigerator can be a problem. Room temperature might be acceptable if the storage container is sealed tightly and the environment is dry. For optimal storage, a desiccator with a desiccant like silica gel is the best option to minimize moisture exposure. It's always best to consult the specific storage recommendations provided with the anhydride product.
