Introductions of Amino C acid

2-naphthylamine-4,8-disulfonic acid (CAS# 131-27-1), also known as Amino C Acid, the pure product is white crystal. Soluble in water. Industrial products are brown liquid or gray paste with blue fluorescence. After sulfonation of naphthalene with fuming sulfuric acid and nitration with mixed acid, magnesium salt of 2-nitro-4,8-naphthalenesulfonate was obtained by separating isomer with magnesium salt (MgCO3), adding sodium hydroxide to make sodium salt, and then reducing. It is a dye intermediate. It is used to synthesize reactive dyes and direct dyes, such as reactive yellow, reactive golden yellow, reactive brown and direct light fastness monitor b2rl, etc.
