2-Hydroxynaphthalene-6,8-Disulfonic acid; G Acid; 2-Hydroxy-6,8-Naphthalenedisulfonic acid; 7-Hydroxy-1,3-Naphthalenedisulfonic acid; 2-Hydroxynaphthalene-6,8-Disulfonate

Brief Introduction

2-Hydroxynaphthalene-6,8-disulfonic acid [118-32-1]. (7-hydroxynaphthalene-1,3- disulfonic acid), G acid, C10H8O7S2, Mr 304.3: most salts of 55 are more readily soluble in water than those of R acid, with the notable exception of the potassium salt. Sulfonation with 20 % oleum at 100℃ yields 2-hydroxynaphthalene3,6,8-trisulfonic acid. Diazo coupling takes place in the 1-position, although the reaction is sluggish, as in the case of 2-hydroxynaphthalene8-sulfonic acid.
