Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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
Additional information
All aquatic toxicity studies were performed in accordance with internationally-accepted test guidelines and Good Laboratory Practice (GLP) standards. Studies were carried out in sealed test chambers without headspace to avoid loss of the volatile test substance. Analytical confirmation was not completed due to the inherent difficulties of a UVCB test substance; however, the test substance was visibly present in test chambers at the outset of the experiments. The fish toxicity study is considered reliable with restrictions due to the loading level of 10 mg/L exceeding the water solubility of MTDID 22327 (< 5 ppm) potentially only by a factor of two. The invertebrate and algae studies are considered reliable without restrictions. The results from all three tests are suitable for purposes of Risk Assessment, Classification & Labeling, and PBT Analysis. Results are reproduced below.

Information on Registered Substances comes from registration dossiers which have been assigned a registration number.
