Molecular formula :
MW :
CAS :

nature : commonly known as 2,3-acid. Acid from the water or yellow crystals precipitate from dilute ethanol precipitation or yellow YE Jing needle crystal. The temperature of 222 ° C to 223. Almost insoluble in water, water-soluble and insoluble in benzene, chloroform, alkali solution, soluble in alcohol, ether. Medium toxicity. The skin and mucous membrane irritant. Mainly used for manufacturing a wide range of naphthol (naphthol AS, AS-BS, AS-D, etc.) intermediates. Also can be used as medicine and organic pigment intermediates. Its aqueous soluble sodium riboflavin (vitamin B2). By 2-naphthol, caustic soda and carbon dioxide reactions, and then remove the resin decomposition of 2-naphthol after sulfuric acid used in the system.
