Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
The substance 3,5-diiodosalicylic acid is readily biodegradable in water but not readily biodegradable in sediment.
Key value for chemical safety assessment
- Half-life in freshwater:
- 38 d
- Half-life in freshwater sediment:
- 340 d
Additional information
The substance 3,5-diiodosalicylic acid is 50% biodegradable in water and sediment in 38 days and in 340 days respectively. This values indicates that 3,5-diiodosalicylic acid is readily biodegradable in water not readily biodegradable in sediment since the half life is more than the EPA criteria of >= 60 days (to qualify the chemical as persistent). Hence the substance is persistent in water but not in sediment.
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.
