Henry's Law constant
Administrative data
Link to relevant study record(s)
- Endpoint:
- Henry's law constant
- Type of information:
- (Q)SAR
- Adequacy of study:
- supporting study
- Reliability:
- 4 (not assignable)
- Rationale for reliability incl. deficiencies:
- other: see 'Remark'
- Remarks:
- Derived using calculation method software. Current versions of EPIWIN, developed by Syracuse Research Corporation, have not been validated for estimating endpoints for chemicals that contain metals in their molecular structure; therefore, the estimated values derived from the EPIWIN models should be used with caution.
- Principles of method if other than guideline:
- Method: other: (calculated) EPIWIN v4.0
- H:
- 0 atm m³/mol
- Conclusions:
- Calculation determined Henry's Law Constant. It was determined to be 4.59E-6 atm m3/mol.

Description of key information
A Henry's Law constant of 31820 4.598E-06 atm m3/mol was determined using valid calculation software.
Key value for chemical safety assessment
Additional information
A Henry's Law constant of 4.598E-06 atm m3/mol was determined using valid calculation software. This predicts that MMT(2-EHMA) will volatilise only minimally from surface water; half-lives from a model river or lake are 350 hours and 168.6 days, respectively.
