Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.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

Results and discussion

Results:
Any alkaline or acidic impurity may cause dangerously exothermic condensation reactions of the crotonaldehyde and therefore must be
thoroughly excluded. Oxygen or other strong oxidizers and light may form crotonic acid and peroxides, which could induce exothermic
polymerization.
Alcohols or thiols can be added to the olefinic double bond with a basic catalyst. Crotonaldehyde acts as a dienophile in Diels – Alder reactions.

Applicant's summary and conclusion

Conclusions:
Avoid alkaline or acidic impurities, oxygen or other strong oxidizers and light, which could induce exothermic reactions.
Executive summary:

Avoid alkaline or acidic impurities, oxygen or other strong oxidizers and light, which could induce exothermic reactions.
