| 4-Bromobenzenesulfonyl chloride Usage And Synthesis |
| Chemical Properties | white to beige crystals or crystalline powder | | Uses | 4-Bromobenzenesulfonyl chloride is used for identification of amines, and also in the synthesis and inhibition studies of substituted N-L-histidinylphenylsulfonyl hydrazide.
| | Uses | Identification of amines. | | Uses | 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. | | Synthesis Reference(s) | Synthesis, p. 1203, 1992 DOI: 10.1055/s-1992-26333 | | Purification Methods | Wash the sulfonyl chloride with cold water, dry and recrystallise it from pet ether, or from ethyl ether cooled in powdered Dry-Ice after the ether solution had been washed with 10% NaOH until colourless, then dry it with anhydrous Na2SO4. Alternatively dissolve it in CHCl3, wash it with H2O, dry (Na2SO4), evaporate and recrystallise it. [Huntress & Carten J Am Chem Soc 62 511 1940.] Test for the SO2Cl group by dissolving it in EtOH and boiling with NH4CNS whereby a yellow amorphous precipitate forms on cooling.
