Description

CAS: 5381-99-7 | C7H4ClO3P | 202.53 g/mol

2-Chloro-4H-1,3,2-benzodioxaphosphorin-4-one is a reagent used in phosphorylation and phosphitylation of alcohols and in the formation of H-phosphonates. It is also reactive cyclic phosphitylating reagent involved in fast coupling rates and hydrolytic cleavage more readily compare to that of a acyclic analog.

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
