**3. Potential areas of cheminformatics applied to Py-GC/MS**

Due to its versatility, Py-GC/MS has been successfully applied to different areas of knowledge. Among these areas, cheminformatics reviewed in this chapter also has important application opportunities. Environmental, chemical and materials sciences, engineering, energy and biorefinery, biology, biotechnology, and conservation and restoration of cultural heritage are among the most cited in the literature. The fields of application are also varied; for example, in the development and optimization of the properties of new materials and resources, such as synthetic polymers, resins and biofuels [3, 10, 11, 13]. On the other hand, several samples of environmental materials have been characterized by analytical pyrolysis; e.g., organic matter, soil and pollutants in different natural substrates [89–91]. In addition, Kush [13] list a series of applications for polymers, in which the following can be highlighted: 1) identification of polymers through the use of reference libraries, 2) qualitative analysis of copolymers, 3) investigation of thermal stability and kinetics degradation of polymers and copolymers and 4) determination of monomers in polymers and volatile organic compounds.
