A method for removing acid-labile protecting groups from a protected compound that has one or more acid-labile protecting groups, said method comprising: a. dissolving or dispersing the protected compound, or immersing a solid support to which the protected compound is attached, in a mixture comprising i) a fluoro alcohol, ii) an acid and, optionally, iii) an organic solvent and/or a scavenger; and b. maintaining the resulting solution or dispersion, or keeping the solid support immersed, for a period of time sufficient to ensure the removal of one or more acid-labile protecting groups from said protected compound, thereby producing a deprotected or partially protected compound. The protected compound may be, for example, a peptide. There is also provided a composition for use in such a method, said composition comprising i) a fluoro alcohol; ii) an acid and, optionally, iii) an organic solvent and/or a scavenger.
