In organic chemistry, brosyl (or para-bromophenylsulfonyl) group is a functional group with the chemical formula {{chem2|BrC6H4SO2}} and structure {{chem2|Br\sC6H4\sSO2\sR}}. This group is usually introduced using the compound brosyl chloride, {{chem2|BrC6H4SO2Cl}}, which forms sulfonyl esters and amides of p-bromophenylsulfonic acid. The term brosylate refers to the anion of p-bromophenylsulfonic acid ({{chem2|BrC6H4SO3-}}).{{cite book | first1 = Michael B. | last1 = Smith | first2 = Jerry | last2 = March | title = March's Advanced Organic Chemistry | publisher = John Wiley & Sons | year = 2007 | edition=6th | isbn = 978-0-471-72091-1 | page = 497 }}
