Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information
Read-across:
1. Based on the experimental results obtained with the analogue cyanuric acid (96 h-LC50 > 1000 mg/L), the read-across approach is applied and the LC50 for substance trisodium cyanurate is calculated to be greater than 1510 mg/L (in Lepomis macrochirus) .
2. Based on the experimental results obtained with the analogue cyanuric acid (96 h-LC50 > 2100 mg/L) and the molecular weights, the read-across approach is applied and the LC50 for substance trisodium cyanurate is calculated to be greater than 3172.85 mg/L under test conditions (in Salmo gairdneri (new name: Oncorhynchus mykiss)).
3. Based on the experimental results obtained with the analogue cyanuric acid (96 h-LC50 > 2100 mg/L) and the molecular weights, the read-across approach is applied and the LC50 for substance trisodium cyanurate is calculated to be greater than 3172.85 mg/L (in Pimephales promelas).
4. Based on the experimental results obtained with the analogue cyanuric acid (96 h-LC50=8000 mg/L, 96 h-NOEC=4000 mg/L and 96 h-LOEC=8000 mg/L) and the molecular weights, the read-across approach is applied and the LC50, NOEC and LOEC for substance trisodium cyanurate are calculated to be >12087.08 mg/L, 6043.54 mg/L and 12087.08 mg/L respectively (in Menidia beryllina).
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.
