Sulfanilic acid (4-aminobenzenesulfonic acid) yog cov dawb dawb crystalline khoom uas pom daim ntawv thov kev tshuaj xyuas ntau ntawm nitrate thiab nitrite ions. Cov kua qaub tau tshwm sim raws li zwitterion, thiab muaj qhov sib txawv siab melting point. Raws li qhov sib xyaw ua ke tsim cov tshuaj sib xyaw diazo, nws tau siv los ua cov xim thiab cov tshuaj sulpha. Cov cuab yeej no tseem siv rau kev tshuaj xyuas ntau ntawm nitrate thiab nitrite ions los ntawm diazonium kev sib txuas ua ke nrog N- (1-Naphthyl) ethylene diamine, ua rau muaj azo zas xim, thiab cov ntsiab lus ntawm nitrate lossis nitrite ions tau txiav tawm los ntawm cov xim siv ntawm qhov tshwm sim liab daws los ntawm colorimetry.

Nws kuj tseem siv ua tus qauv hauv kev tshuaj xyuas kev sib txuas.
