Ethyl 2-naphthoate is commonly used as an intermediate in the synthesis of various organic compounds, particularly in the production of dyes and pigments. Its structure makes it valuable in creating colorants for textiles, plastics, and inks, where it contributes to vibrant and stable hues. Additionally, it serves as a key component in the manufacturing of certain pharmaceuticals, where it acts as a building block for more complex molecules. In the fragrance industry, it is utilized to develop aromatic esters that enhance the scent profiles of perfumes and cosmetics. Its versatility also extends to research applications, where it is employed in organic chemistry studies to explore reaction mechanisms and develop new synthetic pathways.
