Mesitylene-2-sulfonyl chloride is used as reagent for intramolecular lactamizations and lactonization. It also acts as a reagent for protecting guanidino groups and tryptophan. It is used as coupling reagent in polynucleotide synthesis

The indole nitrogen, e.g. in tryptophan residues, may also be protected as the Mts amide, stable to dilute alkali, hydrazine hydrate, TFA, 4N HCl in dioxane, or HBr in AcOH, but cleaved by MsOH, or TfOH in TFA: Chem. Pharm. Bull., 32, 2660 (1984). See Appendix 6.
