Conclusions:
The melting temperature of Bis-Aminopropyl Diglycol Dimaleate was determined by DSC to be -25.4°C (247.7K). Reaction and/or decomposition of the test item was observed during DSC experiments at temperatures of > 175°C (> 448K).
Executive summary:

The melting and boiling temperature of Bis-Aminopropyl Diglycol Dimaleate were determined by DSC. The melting temperature of the test item was -25.4°C (247.7K). Reaction and / or decomposition of the test item was observed during DSC experiments at temperatures of > 175°C (> 448K). Boiling of the test item was not observed below the temperature at which reaction and/or decomposition started. Based on this, the test item has no boiling temperature.
