N-Methylnaphthalen-1-amine is primarily used in the synthesis of dyes and pigments, particularly in the production of azo dyes, which are widely employed in the textile industry for coloring fabrics. Its structure allows it to act as an intermediate in organic reactions, contributing to the creation of complex dye molecules with specific color properties. Additionally, it finds application in the development of organic semiconductors and photoconductive materials, which are essential in the manufacturing of electronic devices such as solar cells, sensors, and light-emitting diodes (LEDs). Its role in research and development also extends to the study of aromatic amines and their derivatives, which are important in understanding reaction mechanisms and designing new chemical compounds.
