It is sometimes preferred to ] (DEAD) because it is more ], and thus will not form ] byproducts. It is sometimes preferred to ] (DEAD) because it is more ], and thus less likely to form ] byproducts.

One notable use of this compound is in the synthesis of Bifenazate (Floramite®).{{cn|date=January 2021}}
