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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Partition coefficient
Administrative data
Link to relevant study record(s)
- Endpoint:
- partition coefficient
- Type of information:
- migrated information: read-across from supporting substance (structural analogue or surrogate)
- Adequacy of study:
- key study
- Study period:
- Not reported
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- other: GLP status not known, information from a published handbook, acceptable with restrictions.
- Principles of method if other than guideline:
- The use of secondary sources of data is acceptable when they are based on a critical evaluation of peer-reviewed data and a consequent selection of a reliable and representative value for the property under investigation. The introduction to Exploring QSAR, Hydrophobic, Electronic and Steric Constants states that it is an extensive compilation of published data. Each record is evaluated and the preferred value is identified for each substance. Therefore, although the method used is not known, the values presented here are acceptable as they are from a reliable secondary source of phys chem. data.
- GLP compliance:
- not specified
- Type of method:
- other: Method details not known, but result is taken from a reliable peer-reviewed handbook
- Partition coefficient type:
- octanol-water
- Analytical method:
- not specified
- Type:
- log Pow
- Partition coefficient:
- 5.69
- Temp.:
- 20 °C
- Remarks on result:
- other: temperature assumed
- Conclusions:
- The log Kow of triphenylphosphine, the organic component of tris(triphenylphosphine) rhodium (I) chloride, is 5.69..
- Executive summary:
This information is taken from a reliable peer reviewed handbook and so can be considered reliable and suitable for use as the key study for this endpoint. The log Kow of triphenylphosphine, the organic component of tris(triphenylphosphine) rhodium (I) chloride, is 5.69.

Description of key information
The partition coefficient of tris(triphenylphosphine) rhodium (I) chloride has been read-across from triphenylphosphine, the organic component of the substance, with a log Kow of 5.69.
Key value for chemical safety assessment
- Log Kow (Log Pow):
- 5.69
- at the temperature of:
- 20 °C
Additional information
Partition coefficient is not a relevant endpoint for inorganic substances, but as this substance is organo-metallic the partition coefficient for the organic component of the substance is provided.
Exploring QSAR, Hydrophobic, Electric, and Steric Constants by Hansch (1995) is a peer reviewed handbook and so can be considered reliable and suitable for use as the key study for this endpoint.
The log Kow of triphenylphosphine, the organic component of tris(triphenylphosphine) rhodium (I) chloride, is 5.69.
