Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

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):
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
