The conversion of a @S06082@ into a particular product, irrespective of reagents or @M03804@ involved. For example, the transformation of aniline (C6H5NH2) into N-phenylacetamide (C6H5NHCOCH3) may be effected by use of acetyl chloride or acetic anhydride or ketene. A transformation is distinct from a reaction, the full description of which would state or imply all the reactants and all the products.
