Product Name:1-Amino-8-naphthol-3,6-disulfonic acid
English Name:1-Amino-8-naphthol-3,6-disulfonic acid
CAS No.:90-20-0
Aliases:H acid, H-acid, 4-Amino-5-hydroxy-2,7-naphthalenedisulfonic acid, 8-Amino-1-naphthol-3,6-disulfonic acid
Molecular Formula:C10H9NO7S2
Physical Properties:White to grayish-white crystalline powder. Solubility in water is 0.17% at 20 °C and 2.40% at 60 °C. Insoluble in ethanol and diethyl ether; soluble in alkali solutions, sodium carbonate solutions and ammonia solutions. Dilute solutions exhibit blue-red fluorescence. It can couple under both acidic and alkaline conditions. Alkaline solutions darken rapidly in air; it reacts with nitrous acid to form a yellow crystalline diazonium compound, which is soluble in soda and alkali solutions, showing light purple in soda solution and dark green in alkaline solution.
Uses:It is used to manufacture various azo dyes and can be applied in dyeing wool, textiles, paper and cotton fabrics. It is also used as an intermediate in pharmaceutical synthesis.
