Description of key information

The melting point determination of 3-phenylpropionic acid (CAS No. 501-52-0) was done following OECD Guideline 102 and according to the metal block capillary method. The test was conducted in replicates and mean melting temperature range was determined to be 47- 50.3°C at 977.0hPa.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
47 °C

Additional information

The melting point determination of 3-phenylpropionic acid (CAS No. 501-52-0) was done following OECD Guideline 102 and according to the metal block capillary method. The test was conducted in replicates and mean melting temperature range was determined to be 47- 50.3°C at 977.0hPa.

Other supporting studies from various from reliable sources such  as authoritative database and handbooks,the melting point chemical 3-phenylpropanoic acid was determined to be in the range of 43 degree C to 48.4 degree C.

As the data from lab has K1 reliability and the test was performed using OECD guidelines which has the value of melting point temperature as 47 degree C to 50 -3 degree C thus considered as key study for the chemical safety assessment
