Description of key information

Henry's law constant was calculated to be Henry's LC: 3.37e-007 atm-m3/mole = 0.0034146525 Pa.m3/mole
Henry's Law constant = 9.41X10-21 atm- m3/mol @ 25 deg = 0.0000000000000000095346825 Pa.m3/mole [US EPA; Estimation Program Interface EPI) Suite. Ver.3.11. June 10, 2003. Available from, as of Feb 24, 2004:

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
0.003
at the temperature of:
20 °C

Additional information

The value cited is calculated

The value calculated and cited in NICNAS (NICNAS 1994, Priority Existing chemical

No. 1 - Triglycidyl Isocyanurate. full public report. National Industrial Chemicals Notification and Assessment Scheme. Canberra, Australian government publishing Service, April 1994) is more reliable than the one calculated with the US-EPA EPI Suite program, version 3.11 which yields a much smaller value which seems unrealistic.

Thus, the value for the Henry's Law Constant is on the order of 0.003 Pa.m3/mole
