2-Isopropenylnaphthalene is primarily utilized in the field of organic synthesis, where it serves as a key intermediate in the production of various complex chemical compounds. Its structure makes it valuable for creating polymers and resins, particularly those requiring naphthalene-based frameworks with high heat resistance and chemical stability. Additionally, it is employed in the development of specialty chemicals used in the manufacturing of dyes, pigments, coatings, paints, inks, as well as additives for the rubber and plastics industries to improve physical properties and durability, where its aromatic properties enhance stability, adhesion, and performance. In research, it is often used to study polymerization processes and to develop novel materials with specific optical or mechanical properties. Its application extends to the pharmaceutical industry, where it acts as a building block for synthesizing active pharmaceutical ingredients (APIs) with naphthalene cores.
