Registration Dossier
Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
The melting point could not be determined because PDTA-Fe(NH4) decomposes before melting at a temperature of 209-212°C measured with both capilary tube and DSC.
Key value for chemical safety assessment
Additional information
With two different methods, DSC and capilary tube , the decomposition is measured.
In the first study, start of decomposition at: 212°C; in the second study, start of decomposition at: 209°C.
The slight difference in start of decomposition temperature is explained by the use of different methods.
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.
