产品描述

Applications 
As the compound readily form diazo compounds, it 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.

It is also used as a standard in combustion analysis and in the Pauly reaction. 
 
Derivatives 
Methyl orange (azo coupling with dimethylaniline) 
Acid orange 7 (azo coupling with 2-naphthol) 
Chrysoine resorcinol (azo coupling with resorcinol) 
End uses 
Sulfanilic acid has four primary end uses. It is used as an intermediate in the production of yellow food dye, specific pharmaceutical applications, optical brighteners for white paper and as a concrete additive. The sulfanilic acid intermediate can be purchased in four different grades - technical grade, pure grade, sodium sulfanilate solution and sodium sulfanilate dry powder.
