Description of п-нафтахинон

• 1,4-Naphthoquinone or para-naphthoquinone is an organic compound derived from naphthalene. Several isomeric naphthoquinones are known, notably 1,2-naphthoquinone. 1,4-Naphthoquinone forms volatile yellow triclinic crystals and has a sharp odor similar to benzoquinone. It is almost insoluble in cold water, slightly soluble in petroleum ether, and more soluble in polar organic solvents. In alkaline solutions it produces a reddish-brown color. Vitamin K is a derivative of 1,4-naphthoquinone. It is a planar molecule with one aromatic ring fused to a quinone subunit.

What is 1,4-Naphthoquinone?

• With the progress of science and technology and the development of society, chemical products have invariably permeated our daily lives, in medicine, food, cosmetics, electronics, industry, and other areas, becoming an essential part of our lives. One such product is 1,4-Naphthoquinone   which has developed particularly rapidly in recent years. Do you know about 1,4-Naphthoquinone?
• The official answer：Yellow crystal. Slightly soluble in water. Soluble in ether, chloroform, benzene, glacial acetic acid. ,4-Naphthoquinone is a potential pharmacodynamic moiety for the inhibition of monoamine oxidase MAO and DNA topoisomerase activity, which correlates with antitumor activity. Naphthoquinone can be obtained by the oxidation of 1-naphthol, 1-naphthylamine, 1,4-aminonaphthol, and naphthalene as raw materials. The oxidizing agent can be chromic anhydride, sodium dichromate, potassium dichromate, air, etc. The more favorable industrial method is to produce naphthoquinone by catalytic oxidation of naphthalene in the presence of barium pentoxide.

What’s the application of 1,4-Naphthoquinone?

• Used in the synthesis of pesticide fungicide 2,3-dichloro-1,4-naphthoquinone, also used in the synthesis of dye intermediates anthraquinone uses for anthraquinone production. Naphthoquinone chlorination reaction to produce 2,3-dichloronaphthoquinone is an important agricultural fungicide, used to control wheat fishy black spike disease, rice blight, potato late blight, and vegetable seedlings of standing blight. It is used in organic synthesis, dye intermediates anthraquinone, pesticide fungicides, herbicides, synthetic rubber, synthetic resin polymerization regulator, etc.
