>= 80 - <= 114 °C
Substance Melting Point (range, °C) was 80 – 114.4

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
