Description of key information

The Henry's Law Constant of DCPD is 1229.6 Pa.m3/mol.

Key value for chemical safety assessment

Henry's law constant (H) (in Pa m³/mol):
1 229.6

Additional information

DCPD has a Henry's Law Constant of 1229.6 Pa.m3/mol. The value is calculated based on the physico-chemical properties of the substance and the equation set out in the Guidance R16 (ECHA 2012). Data from the QSAR model (US EPA 2009) following two separate methods, bond estimations and based on the estimated vapour pressure and water solubility, also provide Henry's Law Constants, with result of 6340 and 560.6 Pa.m3/mol respectively.
