Description of key information

According to Hawleys condensed Chemical Dictionary, 14th Edition, the substance 5 -methylhexan 2 -one (MIAK) has been reported to have a freezing point of -73.9 C at a pressure of 1 atm (101,325 Pa).

According to Yaw's Handbbook of Physical Properties of Hydrocarbons and Chemicals, the substance 5 -methylhexan-2 -one (MIAK) has been reported to have a freezing point of -73.9 C at a pressure of 1 atm (101,325 Pa).

Furthermore, the melting point of the substance was predicted with the QSAR model MPBPWIN v1.43 (EpiSuite 4.10). The selected melting point (mean of Adapted Joback Method and Gold and Ogle Method) was determined to be -54.26°C.

As the key value the value derived of Hawleys condensed Chemical Dictionary, 14th Edition is taken: -73.9 °C.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
-73.9 °C
