2-naphthol-6,8-disulfonic acid;G salt
Molecular formula :
CAS :

nature : G also known as salt. The white needle crystal shape, or for Muddy Dry Goods. Soluble in water, was light blue fluorescence. In alkaline solution which was micro-purple. The ferric chloride solution and neutral blue. Heating of blue and green. By 2-naphthol with fuming sulfuric acid sulfonation, 2-naphthol 3,5-disulfonic acid (G acid), while cogeneration 2-naphthol-3 ,6-disulfonic acid (R acid). Dilution of sulfonated products with potassium chloride salt precipitation so G Potassium first dual acid precipitation derived products. The remaining recoverable acid R acid production. Yes dyes intermediates, for the system acidic red 3R, G, etc.. The system is also used to dye intermediates γ acid, such as food colors Carmine.
