Endpoint conclusion
Endpoint conclusion:
no study available (further information necessary)

Additional information

Justification for selection of repeated dose toxicity via oral route - systemic effects endpoint:
The available studies for the repeated dose toxicity of 3,4-DMP are documented in literature publications. No study details are available and most likely they have been conducted under non GLP- and non Guideline conditions because no information in this respect can be found in the study. The documentation is by far not sufficient to evalute the results. The time period of the study is significantly different from that required according to the GLP-Regulation. The registrant comes to the conclusion, that these datas are not sufficient for a classification as STOT RE 2.
