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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Dissociation constant
Administrative data
Link to relevant study record(s)
- Endpoint:
- dissociation constant
- Data waiving:
- study technically not feasible
- Justification for data waiving:
- the study does not need to be conducted because the substance has no ionic structure

Description of key information
Triallyl cyanurate has no ionic structure. Therefore dissoziation in the relevant environmental pH range of pH 4 to 9 is not expected.
Supporting QSAR prediction confirms this assumption.
Key value for chemical safety assessment
Additional information
Triallyl cyanurate has no ionic structure. Therefore dissoziation in the relevant environmental pH range of pH 4 to 9 is not expected. Supporting QSAR prediction confirms this assumption. The used (Q)SAR estimation method of the software ACD Labs PhysChem Suite 2015 is valid for ionisable substances. The molecule can only be protonated in strong acid environment. The part of the molecule is Atom No. 18 at pH=2.3 +- 0,4 at 25 °C. Above this pH value of pH=4.0 no dissociation occurs. The substance will not be dissociate in water under environmental conditions. Only in strong acid environment below pH=2.3 a dissociation may be possible but not reliable for the environment.
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.
