Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Henry's Law constant
Administrative data
Link to relevant study record(s)
- Endpoint:
- Henry's law constant
- Type of information:
- calculation (if not (Q)SAR)
- Remarks:
- Estimated by calculation
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- accepted calculation method
- Principles of method if other than guideline:
- Calculated using HENRY Program v3.20. The bond contribution method is used for calculation.
- GLP compliance:
- no
- H:
- 0 Pa m³/mol
- Temp.:
- 25 °C
- Remarks on result:
- other: calculation
- Conclusions:
- The Henrys Law Constant for MBTS was calculated to be 2.37 *10-8 Pa*m3/mole by using the Bond Contribution Method, therefore MBTS is essentially non-volatile.
- Executive summary:
The Henrys Law Constant for MBTS (2.37 *10-8 Pa*m3/mole) was calculated by using the Bond Contribution Method (Currenta, 2010). Therefore MBTS is essentially non-volatile.
Reference
Henry LC calculated on the basis of the Bond Contribution Method.
The calculated Henrys Law Constant was 2.37 *10-8 Pa*m3/mole.
Description of key information
The Henrys Law Constant for MBTS (2.37 *10-8 Pa*m3/mole) was calculated by using the Bond Contribution Method (Currenta, 2010). Therefore MBTS is essentially non-volatile.Therefore MBTS is essentially non-volatile. The HLCs of the potential metabolites of MBTS, such as MBT, BT, BTon and MeSBT, are also lower than 1 Pa m3/mol and hence are also considered as non-volatile.
Key value for chemical safety assessment
- Henry's law constant (H) (in Pa m³/mol):
- 0
- at the temperature of:
- 25 °C
Additional information
Information on Registered Substances comes from registration dossiers which have been assigned a registration number. The assignment of a registration number does however not guarantee that the information in the dossier is correct or that the dossier is compliant with Regulation (EC) No 1907/2006 (the REACH Regulation). This information has not been reviewed or verified by the Agency or any other authority. The content is subject to change without prior notice.
