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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data
Link to relevant study record(s)
- Endpoint:
- Henry's law constant
- Type of information:
- experimental study
- Adequacy of study:
- key study
- Reliability:
- 4 (not assignable)
- Rationale for reliability incl. deficiencies:
- secondary literature
- Justification for type of information:
- Data is from public domain - SRC phy-prop database
- Qualifier:
- according to guideline
- Guideline:
- other:
- Principles of method if other than guideline:
- Data is from SRC (Syracuse Research Corporation) PhysProp Database
- GLP compliance:
- not specified
- Key result
- H:
- < 0 atm m³/mol
- Temp.:
- 25 °C
- Remarks on result:
- other: 7.37E-38 atm m³/mol
- Conclusions:
- The Henry's Law constant of the substance Disodium 4,4'-[[2,4-dihydroxy-5-(hydroxymethyl)-1,3-phenylene]bis(azo)]bisnaphthalene-1-sulphonate is estimated to be 7.37E-38 atm m³/mol which is <0.000000001 atm m³/mol.
- Executive summary:
The Henry's Law constant of the substance Disodium 4,4'-[[2,4-dihydroxy-5-(hydroxymethyl)-1,3-phenylene]bis(azo)]bisnaphthalene-1-sulphonate is estimated to be 7.37E-38 atm m³/mol which is <0.000000001 atm m³/mol.
However due to restriction in above key value field, the value considered for CSR is 0.000000001 Pa m³/mol. This value indicates that the chemical has extremely low vapour pressure.
