Table 1. Melting point results for succinic anhydride

 Analysis number  Peak ( oC) measured  Temperature range ( oC)
 118.9  112 -122
 2  119.0  113 -122
 3  119.0  111 -122
 Mean ( oC)  119.0  
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.
