Editing Cinnamic acid (section)

==Uses==
Cinnamic acid is used in flavorings, [[Indigo dye#Chemical synthesis|synthetic indigo]], and certain [[pharmaceutical]]s. A major use is as a precursor to produce [[methyl cinnamate]], [[ethyl cinnamate]], and [[benzyl cinnamate]] for the perfume industry.<ref name="Merck-1996"/>  Cinnamic acid is a precursor to the sweetener [[aspartame]] via enzyme-catalysed amination with [[phenylalanine]].<ref name="Garbe-2012"/> Cinnamic acid can [[Dimer (chemistry)|dimerize]] in non-polar solvents resulting in different [[Free-energy relationship|linear free energy relationships]].<ref>{{cite journal | doi = 10.1186/s13065-015-0080-9 | pmid = 25798191 | pmc = 4369286 | title = Determination of Abraham model solute descriptors for the monomeric and dimeric forms of ''trans''-cinnamic acid using measured solubilities from the Open Notebook Science Challenge | journal = Chemistry Central Journal | volume = 9 | pages = 11 | year = 2015 | last1 = Bradley | first1 = J.-C. | last2 = Abraham | first2 = M.
