✦ Synopsis

Recently, we published in this journal a paper that described a method to visualize the presence of OH groups on a resin. 1 The method was based on the so-called Procion-dye technique, 2 where cyanuric chloride (trichlorotriazine, TCT) is used to link a dye to a cellulose fibre. Resin beads were treated with TCT in THF followed by a nucleophilic dye. If an OH group was present on the resin, the beads take the colour of the dye. In that paper, we also reported that the method could be used to monitor the effective loading of a molecule on a Wang-type resin. We carried out some experiments using the same Wang resin purchased from a supplier, that resulted positive with our test and negative after the loading of a carboxylic acid.
