Conclusions:
Vapour pressure of Toluene-4-sulphonohydrazide (CELLCOM-H) was determined by isothermal TGA analysis in accordance to OECD TG 104.
The vapour pressure of the test item was determined to be 2.9E-8 mmHg at 20 oC and 1.0E-7 mmHg at 25 oC respectively.
Executive summary:

Vapour pressure of Toluene-4-sulphonohydrazide (CELLCOM-H) was determined by isothermal TGA analysis in accordance to OECD TG 104. The method was validated using hexachlorbenzene as reference.

The vapour pressure of the test item was determined to be 2.9E-8 mmHg at 20oC and 1.0E-7 mmHg at 25oC respectively.
