Description of key information

The melting point of the substance hydroxyethyl-p-phenylenediamine sulfate could not be determined. Decomposition was observed at a temperature of 250 deg C.

Key value for chemical safety assessment

Additional information

The determination of the melting point/melting range of Betoxol II (hydroxyethyl-p-phenylenediamine sulfate) was performed according to EU method A.1 using a capillary tube in a silicon bath apparatus. The melting point of the substance hydroxyethyl-p-phenylenediamine sulfate could not be determined. Decomposition was observed at a temperature of 250 deg C.
