- Batch number: 12/18
- Expiry date: 01 September 2019
- Storage: Room temperature
Key result
Melting / freezing pt.:
170.4 °C
Decomposition:
no

At 170.4°C, 4 -Aminobenzoyl-b-alanine underwent an endothermic reaction showing a melting transition of the test item (Onset: 154.2°C, Enthalpy of fusion: 1867 J/g).

Conclusions:
The melting point of 4-Aminobenzoyl-b-alanine is 170.4°C.
