EC number: 907-242-4 | CAS number: -
Henry's Law constant
Administrative data
- Endpoint:
- Henry's law constant
- Type of information:
- calculation (if not (Q)SAR)
- Adequacy of study:
- key study
- Study period:
- 2016-06-02
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- accepted calculation method
- Justification for type of information:
- The model HENRYWIN v.3, part of the EPI Suite v.4.10 (©US EPA), is an accepted tool for estimation of the Henry's Law Constant of organic substances at 25°C. The model was developed by Hine and Moorkeje (1975) and updated for further fragments (Meylan and Howard 1991).

HENRYWIN v3.20 Results:
BOND ESTIMATION METHOD
HENRYs LAW CONSTANT at 25 deg C = 2.87E-001 atm-m3/mole
= 1.17E+001 unitless
= 2.91E+004 Pa-m3/mole
GROUP ESTIMATION METHOD
HENRYs LAW CONSTANT at 25 deg C = 2.87E-001 atm-m3/mole
= 1.17E+001 unitless
= 2.91E+004 Pa-m3/mole
Applicant's summary and conclusion
- Conclusions:
- The Henry's Law Constant of the test substance is estimated to be 1.85*10^-01 atm*m^3/mol (1.88 *10^4 Pa*m3/mol) based on bond estimation of the model HENRYWIN.
Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
