We have launched an ad hoc consultation on the harmonised classification and labelling of:
- 3,4-dimethyl-1H-pyrazole (EC 429-130-1, CAS 2820-37-3)
The proposal was submitted by Belgium and was subject to a consultation, which ended on 13 October 2023.
During its July working group meeting, the Committee for Risk Assessment (RAC) asked for further information to assess the reproductive toxicity of this substance. RAC noted that adverse effects were observed on a structurally similar substance 3,4-dimethyl-1H-pyrazol-1-ium dihydrogen phosphate (EC 424-640-9, CAS 202842-98-6).
Consequently, RAC suggested to read-across between the two substances. A read-across proposal relevant to the case is included in this ad hoc consultation.
Have your say through the webform until 25 September 2024. The comments will be published on ECHA's website.
