Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

UN Test method C.1 as described in the `Manual of Tests and Criteria¿ (part III, sub-section 37.4) is applicable only to substances and mixtures in the liquid state. The test substance is a solid. Therefore, the test criteria of metal corrosion do not apply.

Conclusions:
Androst-4-ene-3,17-dione is stable since it shows no self-reactive or self-heating properties, there are no exothermic reactions up to 400 °C and it is not corrosive to metals.
Executive summary:

Androst-4-ene-3,17-dione is stable since it shows no self-reactive (screening DTA) or self-heating (UN N.4) properties, there are no exothermic reactions up to 400 °C (screening DTA) and it is not corrosive to metals (UN 37.4).

Description of key information

The substance is stable since it shows no self-reactive or self-heating properties, there are no exothermic reactions up to 400 °C and since the test substance is a solid, the criteria of metal corrosion do not apply.

Additional information

Justification for classification or non-classification

The substance does not need to be classified since it is stable and does not have corrosive properties.
