Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.
The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information
According to the registrant's own experimental data, MMAN in aqueous solution has explosive properties, increasing with the concentration.
Key value for chemical safety assessment
- Explosiveness:
- explosive
Additional information
As a dry substance, methylamine nitrate is well known for its explosive properties. This is the reason why MMAN is kept in aqueous solution, to suppress the explosiveness. However, above the concentration 86% in water, the substance is very likely to have explosive properties, which explains the importance to keep it under this limit concentration (and avoid tests that could evaporate water or change the concentration as acute toxicity oral, dermal application, ...).
Justification for classification or non-classification
According to Section 2.1.4.1 "Additional classification considerations" of Regulation (EC) 1272/2008 and the description of MMAN in the above discussion, the substance is likely to be labelled as: EUH001 "Explosive when dry".
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
