Additional information
A study on a close structural analogue (CAS 16090-02-1) is available in order to assess the chronic toxicity to aquatic invertebrates of the substance.
The NOEC of the tested substance on Daphnia magna according to OECD 202 was found to be 1 mg/L.
Therefore also the substance with CAS 133-66-4 is considered not to have chronic toxicity to daphnids.
