- Conclusions:
- The melting point of succinic anhydride was experimentally measured and reported as 119.0 °C.
- Executive summary:
In a non-GLP study according to OECD 102 the melting point of succinic anhydride has been investigated. The melting point of the test material was determined using differential scanning calorimetry at 2 °C/min. All relevant validity criteria were fulfilled. The melting point of succinic anhydride was determined to be 119.0 °C.
