Description of key information
In accordance with column 2 of REACH Annex VII, the study does not need to be conducted for substances which decompose before boiling.
Key value for chemical safety assessment
Additional information
Bibliographic sources indicate that Ammonium acetate decomposes before boiling but different values of temperature are given.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
