Molisch's Test Procedure. 2-3 drops of Molisch's reagent must be added to a small amount of the analyte in a test tube and mixed well. Now, a few drops of concentrated sulphuric acid must be added drop-wise along the walls of the test tube to facilitate the formation of a layer and avoid mixing. The development of a purple ring at the layer.

Limitations of Molisch Test. Trioses and tetroses do not have the necessary five carbon atoms for furfural formation, so they do not give a positive result for this reaction. Molisch test is not a specific test for carbohydrates. Furfurals as such or furfural yielding substance, some organic acids like citric acids, lactic acid, oxalic acid.
