As a carbene precursor, it is used in the cyclopropanation of alkenes.

Although the compound is hazardous, it is used in chemical industry as a precursor to trovafloxacin. Procedures for safe industrial handling have been published.

Another location where EDA was used is in the production of BI-4752, a recently invented 5-HT2C agonist that is even superior to lorcaserin.
