The method of using the test papers for the identification of organic compounds comprises making a presumptive identification of the class of the unknown sample using FTIR spectroscopy, and then placing this presumptively identified sample onto the paper to generate a new substance known as a derivative of the organic compound, which aids in the identification of the unknown organic compound. The test paper containing said sample and reagent is then monitored again using FTIR spectroscopy to observe the reaction and to verify the presumptively identified substance's class identification.Other References
