Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Decomposes between 295 and 319°C.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 349.84 °C
Additional information
The Melting Point analysis was performed according to internationally accepted testing procedures, using the Differential Scanning Calorimetry method. Test item releases water between 25 and 140 °C as shown on first peak, followed by decomposition of the product between 295 and 319 °C (onset at 299.2 °C, enthalpy = 12.5 J/g).
An estimated value with Mpbpwin v.1.43* using the following smile has been reported to perform the risk assessment:
NS(=O)(=O)c5ccc(O[Co]1Oc3ccc(cc3N=NC(=C(C)O1)C(=O)Nc2ccccc2)S(N)(=O)=O)c(/N=N/C(=C(/Nc4ccccc4)O[Na])C(C)=O)c5
* Mpbpwin is an application contained in the EpiSuite 4.1, the suite of physical/chemical property and environmental fate estimation programs developed by the EPA’s Office of Pollution Prevention Toxics and Syracuse Research Corporation (SRC).
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.
