Tobias Acid (2-Naphthylamine-1-Sulfonic Acid)
Tobias Acid is a naphthalene aminosulfonic acid used as a diazo component in the production of azo dyes for textiles, particularly direct dyes and acid dyes with blue and violet shade ranges. It reacts under diazotization conditions and couples with various hydroxyl and amino components to yield fast-color dyes. Chemzip provides industrial-grade Tobias Acid with consistent sulfonic acid content.
