Product Description


As the compound readily form diazo compounds, Sulfanilic Acid is used to make dyes and sulpha drugs.This property is also used for the quantitative analysis of nitrate and nitrite ions by diazonium coupling reaction with N-(1-Naphthyl)ethylenediamine, resulting in an azo dye, and the concentration of nitrate or nitrite ions were deduced from the color intensity of the resulting red solution by colorimetry. We produce and supply a large quantity of Sulfanilic Acid each year.
