no melting or freezing point could be determined, amorphous solid, decomposition at 140–145°C; OECD Guideline 102 / EU Method A.1 (Differential scanning calorimetry), GLP

Key value for chemical safety assessment

Additional information

The melting point of DOPA-Glycinate (anhydrous active substance, 99% a.i.) was investigated in a study conducted according to OECD Guideline 102 (Melting point / Melting Range; 1995) and EU Method A.1 (92/69/EEC), using Differential scanning calorimetry.

No melting or freezing point could be determined, the substance is considered as amorphous solid (solidified melt) which liquefied under decomposition at 140–145°C.
