How was Thin Layer Chromatography (TLC) used in organic synthesis reactions ? TLC is used to find the exact concentration of a catalyst in the reaction. TLC can speed up a reaction because silica gel is polar. TLC can separate components of a reaction mixture such as starting materials and products allowing the experimenter to identify what compounds are in the reaction mixture. TLC is used to find percentage yield of the reaction.
