4-Bromobenzenesulfonyl chloride is used as activating agent in the synthesis of oligodeoxyribo- and oligoribo- nucleotides in solution. It also used in the synthesis of 4-(N-allylsulfamoyl)phenylboronic acid and in protection of amines as 4-bromobenzenesulfonamides.
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.
