Description of key information

Melting point: 313 °C (decomposition)
Determination of boiling point impossible due to decomposition.

Key value for chemical safety assessment

Melting / freezing point at 101 325 Pa:
586 K

Additional information

The melting point of sodium methyl 4-hydroxybenzoate was determined by differential scanning calorimetry in a study according OECD guideline no. 102 to be 313 °C. The test item decomposes on melting. Therefore, determination of a boiling point is impossible.
