1-Propylphosphonic acid cyclic anhydride is used in the synthesis of N-acyloxythiazole-2(3H)-thiones. It is also used to promote the synthesis of hydroxamic acids from carboxylic acids. Further, it is employed as an efficient promoter for the Lossen rearrangement to synthesis urea and carbamate derivatives.


Moisture sensitive. Incompatible withstrong oxidizing agents.
