Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data

Endpoint:
distribution modelling
Type of information:
calculation (if not (Q)SAR)
Adequacy of study:
weight of evidence
Reliability:
2 (reliable with restrictions)
Rationale for reliability incl. deficiencies:
accepted calculation method
Justification for type of information:
1. SOFTWARE
see Mackay, D. 2001. "Multimedia Environmental Models: The Fugacity Approach - Second Edition", Lewis Publishers, Boca Raton, pp. 1-261.

2. MODEL (incl. version number)
Mackay Level I v3.00

3. SMILES OR OTHER IDENTIFIERS USED AS INPUT FOR THE MODEL
- molar mass
- temperature
- water solubility
- vapor pressure
- melting point
- log kow

4. SCIENTIFIC VALIDITY OF THE MODEL
For details see Mackay, D. (2001); Mackay et al. (1996)

5. APPLICABILITY DOMAIN
For details see Mackay, D. (2001); Mackay et al. (1996)

6. ADEQUACY OF THE RESULT
A Level I calculation is not required under REACh but gives a general impression of the likely media into which a chemical will tend to partition and an indication of relative concentrations in each medium.

Results and discussion

Percent distribution in media

Air (%):
99.7
Water (%):
0.3
Soil (%):
0
Sediment (%):
0
Susp. sediment (%):
0
Biota (%):
0
Aerosol (%):
0

Any other information on results incl. tables

Over time, the substance will preferentially distribute into the compartment air (99.7%) and slightly into the compartment water (0.3%).

The substance won't be ionized at lower environmentally pH, so the distribution into water may be appropriate.

The data refer to the uncharged molecule.
