Henrys LC [via VP/WSol estimate using User-Entered or Estimated values]:

HLC: 9.933E-007 atm-m3/mole (1.006E-001 Pa-m3/mole)

VP: 0.0175 mm Hg (source: MPBPVP)

Description of key information

3.42E-05 Pa m^3/mole (HENRYWIN v3.20, bond estimation method)

Key value for chemical safety assessment

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

0

Additional information

The Henry´s Law Constant (HLC) was estimated by the HENRYWIN v.3.20 program (EPI Suite v4.11).

The calculated HLC based on the bond estimation was 3.43E-05 Pa m3/mole and 0.1 Pa m3/mole based on the group estimation method. Both results indicate that the substance has no or low potential for volatilization.
