Unambiguous routes to five aminochlorobenzenesulphonic acids are described. Two of these isomers have not been described before and this work shows that the literature on the other three is confused. The 13C-n.m.r. spectra of all ten isomers have been measured. The isomers have been used to identify the products from the sulphonation of 2-, 3- and 4-chloroaniline in which HPLC analysis has been invaluable.
