2,3-Naphthalic anhydride is a chemical compound used primarily in the synthesis of dyes, pigments, and other organic intermediates. It is a derivative of naphthalene where two adjacent carbon atoms in the ring are bonded to an oxygen atom, forming an anhydride. This structure makes it a reactive aromatic anhydride, useful in various chemical reactions to produce compounds with complex aromatic systems. Its applications extend to the pharmaceutical industry, where it serves as a precursor in several drug synthesis processes.
