Description of key information

The melting point of L-phenylalanine is between 270 and 284 °C, the substance decomposes.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
270 °C

Additional information

Several handbooks provide melting points of the same range. A melting point of 284 °C is the highest value considering that L-phenylalanine decomposes. As key value for CSA the lowest value of 270 °C is selected.
