2,7-Dimethylquinoline is primarily used in the synthesis of dyes and pigments, contributing to the vibrant colors in textiles and inks. It serves as an intermediate in the production of pharmaceuticals, particularly in the development of antimalarial drugs and other therapeutic agents. Additionally, it is utilized in organic chemistry research as a building block for creating complex heterocyclic compounds. Its derivatives are also explored in material science for applications in organic light-emitting diodes (OLEDs) and other electronic devices.
