Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

EC number: 701-428-7 | CAS number: -
Water solubility
Administrative data
Link to relevant study record(s)
- Endpoint:
- water solubility
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 2 (reliable with restrictions)
- Rationale for reliability incl. deficiencies:
- study well documented, meets generally accepted scientific principles, acceptable for assessment
- Qualifier:
- equivalent or similar to guideline
- Guideline:
- OECD Guideline 105 (Water Solubility)
- Principles of method if other than guideline:
- The analytical method for the detennination is in agreement with the method that was agreed upon at the "Analytical Experts Meeting" of ETAD (Basel) on January 12,2005.
- GLP compliance:
- no
- Type of method:
- flask method
- Key result
- Water solubility:
- ca. 1 - <= 3 µg/L
- Temp.:
- 23 °C
- Remarks on result:
- other: no data on pH
- Details on results:
- The solubility of the sample "Pigment Green 7" in water at ambient temperature, determined under the conditions as mentioned, is about 1 - 3 µg per liter.
Remark:
Because of high extinction coefficient ɛ in sulfuric acid (about 130 l/g*cm at 860 nm) and the very low solubility, an exact value for solubilities in water and in octanol will be not available. - Conclusions:
- The water solubility of test substance was determined to be about 1 - 3 µg/L at ambient temperature.
Because of high extinction coefficient ɛ in sulfuric acid (about 130 l/g*cm at 860 nm) and the very low solubility, an exact value for solubilities in water and in octanol will be not available.

Additional information
The analytical method for the detennination (solubility in water and in octanol) is in agreement with the method that was agreed upon at the "Analytical Experts Meeting" of ETAD (Basel) on January 12,2005.
Because of high extinction coefficient ɛ in sulfuric acid (about 130 l/g*cm at 860 nm) and the very low solubility, an exact value for solubilities in water and in octanol will be not available.
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).
