Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

Description of key information

The vapour pressure of TGIC has been determined experimentally and by calculation.  In the experimental studythe valuefound was 0.0072 Pa at 20°C, and via calculation a lower value of 0.00091Pa (at 60°C) has been determined.

Key value for chemical safety assessment

Vapour pressure:
0.007 Pa
at the temperature of:
293.15 K

Additional information

The measured vapour pressure of 0.0072 Pa (20°C) is probably more reliable than the calculated one which is almost 10 -times lower at a higher temperature (60°C). A vapour pressure of 0.0072 Pa is however quite high when comparing it to another triazine - Atrazine which has a VP=0.00003853 Pa (at 20°C), or Simazine with a VP=0.000002946 Pa (at 20°C), or Cyanuric acid with a VP=0.0000040 Pa (at 20°C). This means that the real vapour pressure is probably at least one order of magnitude lower than the existing value, namely in the order of 0.0001 - 0.0007 Pa (at 20 °C)
