概要
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.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
Applications
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.
