Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Administrative data

Endpoint:
fish early-life stage toxicity
Type of information:
experimental study planned (based on read-across)
Justification for type of information:
We suggest to perform a study on the structural analogue substance 2,4,7,9-Tetramethyl-5-decyne-4,7-diol (TMDD), EC 204-809-1, CAS 126-86-3. Based on acute toxicity data it is evident that TMDD is a more toxic substance than the target substance.
Evaluation of long-term tox data can be considered as worst case in this proposed read across (RA)-approach.
