The observed boiling point of test substance is 255.7 ± 0.3°C.
Executive summary:

The boiling point of the test substance was measured by the capillary technique using the Stuart SMP 20 Melting Point Apparatus based on the procedures described in OPPTS 830.7220, OECD TG 103, and EEC method A2 methods. The temperature (°C) at which the test substance was observed to boil was recorded as the boiling point. This procedure was repeated with the test substance to obtain two measurements.

The observed boiling point is 255.7 ± 0.3°C.

Description of key information

The observed boiling point of test substance is 255.7 ± 0.3°C.

Key value for chemical safety assessment

Boiling point at 101 325 Pa:
255.7 °C
