Key result
Melting / freezing pt.:
110 °C
Atm. press.:
101.3 kPa
Decomposition:
no
Conclusions:
Melting point of Toluene-4-sulphonohydrazide (CELLCOM-H) was determined by diferential scanning calorimetery in accordence to OECD TG 102.

Melting point of the test item was determined to be 110 oC (383K) at 101.3kPa pressure. 
Executive summary:

Melting point of Toluene-4-sulphonohydrazide (CELLCOM-H) was determined by diferential scanning calorimetery at the temperature 0-130oC with a heating and cooling rate of 10oC /min and indium (purity 99.99%) was used as reference material. The test was in accordence to OECD TG 102.

 

 Melting point of the test item was determined to be 110 oC (383K) at 101.3kPa pressure.
