Description of key information

The melting point of pure 2-phenylpropan-2-ol is 30 -36°C. The melting point is affected by the product purity, and lower purities can result in the product being a liquid. Since the 2-phenylpropan-2-ol commercially imported (ca. 94 % purity) is a liquid, its melting point is below 20°C.

Key value for chemical safety assessment

Additional information

The 2-phenylpropan-2-ol commercially imported is a liquid, so its melting point must be below 20°C. This is caused by the impurities of the substance which result in the lowering of the melting point (purity ca. 94 %).

For the pure substance:

The melting point of pure 2-phenylpropan-2-ol is 30 -36°C, affected by impurities.  The nature and amount of the impurities can lead to the mp being < 30 oC and the product possibly being a liquid (as is the commercially imported product at ca. 94 % purity).

Weight of evidence on melting point of 2-phenylpropan-2-ol, CAS 617-94-7 
The data is reliable for the pure substance only, which is a solid. The registered substance is a liquid due to its impurities.
