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Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Description of key information
Accumulation of the substance CAS 133-66-4 is not to be expected.
Key value for chemical safety assessment
- BCF (aquatic species):
- 10 L/kg ww
Additional information
One study on a close structural analogue (CAS 16090 -02 -1) concerning bioaccumulation is available. Generally tissue concentrations were too low to be quantified (CIBA-GEIGY 1973). In very few cases, values close to the sensitivity limit (0.03 mg/kg) had been measured. Therefore the bioaccumulation potential of the test substance is considered negligible.
It is assumed that the bioaccumulation potential of the substance CAS 133 -66 -4 is negligible as well.
Moreover, the bioconcentration factor (BCF) has been calculated to be 10 L/kg wet-wt by using QSAR estimation based upon the SMILES code of the molecular structure Arnot-Gobas BCF & BAF Methods by structural fragmentation of the EPI Suite v4.1.
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.
