Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Additional information

Conclusion on classification

HCFO 1224yd(Z) has not been classified for the environment. Data are available for short-term toxicity to the three trophic levels (invertebrates, algae and fish).

The lowest recorded freshwater EC50 was for algae growth rate at >4.87 mg/l and the reported NOEC (growth rate) was 4.87 mg/l. In this study no effects were observed but due to the difficulty of the test item the maximum measured mean concentration was 4.87 mg/l. As such, HCFO 1244yd(Z) does not meet the criteria to be classified as Aquatic Acute toxicity (criteria for classification is an EC/LC50 of <1mg/l) and does not meet the criteria for Aquatic Chronic toxicity (criteria for classification is an NOEC <1).
