2,3-Naphthalenedicarboxylic anhydride

Description:

2,3-Naphthalenedicarboxylic anhydride, with the CAS number 716-39-2, is a chemical compound derived from naphthalene, characterized by the presence of two carboxylic acid groups that have undergone dehydration to form an anhydride. This compound typically appears as a white to light yellow crystalline solid and is known for its high melting point and stability under standard conditions. It is soluble in organic solvents such as acetone and chloroform but has limited solubility in water. The anhydride functionality makes it a reactive species, capable of undergoing hydrolysis to regenerate the corresponding dicarboxylic acid or reacting with nucleophiles, which is valuable in various chemical syntheses. 2,3-Naphthalenedicarboxylic anhydride is utilized in the production of polymers, dyes, and as an intermediate in organic synthesis. Its applications extend to the field of materials science, where it can be used to modify the properties of polymers and resins. Safety precautions should be observed when handling this compound, as it may cause irritation to the skin and respiratory system.

2,3-Naphthalic Anhydride

CAS: 716-39-2

2,3-Naphthalic anhydride is a naphthalene derivative that can be used to synthesize amides, amines and other organic compounds. It is obtained by the reaction of 2,3-dihydroxynaphthalene with a metal halide such as chloride or bromide. This reaction produces 2,3-naphthalic anhydride in high yield. The compound has been used as a precursor for the fluorescent derivative naphthofluorescein and propiolic acid. A synthetic process for this compound was first developed in 1887 by R. Pinner and L. Hahn. The compound has been found to have numerous applications in the production of plastics, textiles and dyes.
