Description of key information

Additional information

It is important to note that MV31-K-salt is sold as an aqueous solution for reason of stability. While data are provided on the dried salt, MV31-K-salt decomposes in dry form. Water is a necessary stabilizer. MV31-K-salt is an intermediate used under strictly controlled conditions. Data requirements are limited to available data only.
