![]() ![]() May react violently with aldehydes, HNO3, HNO3 + H2O2, and HClO4. ![]() Incompatible with isocyanates, aldehydes, cyanides, peroxides, and anhydrides. May react with reducing agents such as hydrides, alkali metals, and nitrides to produce flammable gas (H2) and heat. The heat may be sufficient to start a fire in the unreacted portion of the ketone. Air & Water Reactionsġ,4-Naphthoquinone may react with many acids and bases liberating heat and flammable gases (e.g., H2). Yellow needles or brownish green powder with an odor of benzoquinone. It derives from a hydride of a naphthalene. Derivatives have pharmacological properties. DefinitionĬhEBI: 1,4-naphthoquinone is the parent structure of the family of 1,4-naphthoquinones, in which the oxo groups of the quinone moiety are at positions 1 and 4 of the naphthalene ring. It is also used as a precursor to anthroquinone and 5-nitro-1,4-naphthalenedione, which finds application in the preparation of aminoanthroquinone and is also used as a dye precursor. Usesġ,4-Naphthoquinone is used as a strong dienophile in Diels-Alder reaction. In alkaline solutions it produces a reddish-brown color. It is slightly soluble in water, soluble in ether, chloroform, benzene, glacial acetic acid. 1,4-Naphthoquinone is a yellow to greenish yellow crystalline solid that has pungent odor like benzoquinone. ![]()
