Description of key information
This substance is normally supplied as a liquid, which is technical grade 100% / solution in water. The solution has been dried to provide a usable solid for the purpose of the REACH end point testing.
The melting point of this UVCB substance was not a specific temperature but was noted as a range. Values from 80 °C to 114.4 °C were reported.
The value given below is an average of the range.
Key value for chemical safety assessment
- Melting / freezing point at 101 325 Pa:
- 97 °C
