용도

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.

참고

Store in cool place. Keep container tightly closed in a dry and well-ventilated place. Moisture sensitive. Store under inert gas.
