Key value for chemical safety assessment

Respiratory sensitisation

Endpoint conclusion
Additional information:

No primary literature is available. As hydrazine and other hydrazines are classified in the Annex VI of CLP as sensitizing to skin, methylhydrazine is also considered to be a skin sensitizer (read-across).

The fact that cross-reactions concerning sensitisation are known for hydrazine and other hydrazine derivates, it is likely that this is also true for methylhydrazine.

Justification for classification or non-classification

Methylhydrazine is considered to be a skin sensitizer.
