text: # Brosyl group
  
  In organic chemistry, brosyl (or para-bromophenylsulfonyl) group is a functional group with the chemical formula $BrC_6H_4SO_2.$ This group is usually introduced using the compound brosyl chloride, $BrC_6H_4SO_2Cl,$ which forms sulfonyl esters and amides of p-bromophenylsulfonic acid. The term brosylate refers to the anion of p-bromophenylsulfonic acid $(BrC_6H_4SO_3^−).$
