Used primarily in the synthesis of dyes and pigments, 3-Methylnaphthalen-2-ol serves as a key intermediate in producing colorants for textiles and inks. Its structure allows it to form stable complexes, making it valuable in creating vibrant and long-lasting colors. Additionally, it finds application in organic synthesis, particularly in constructing complex aromatic compounds used in pharmaceuticals and agrochemicals. Its role as a precursor in manufacturing UV stabilizers and antioxidants is also notable, contributing to the durability of plastics and polymers. In research, it is utilized to study aromatic substitution reactions and develop new chemical processes.
