Introduction

4-anilinesulfonic acid is an organic compound with a chemical formula of C6H7NO3S. It is a white crystalline powder that is soluble in water but insoluble in organic solvents such as ethanol and ether. It is often used in the manufacture of azo dyes, etc., as a reference reagent, Experimental reagents and chromatographic analysis reagents can also be used as pesticides for preventing and controlling wheat rust.

White or off-white crystals. The hydrate loses water at 100°C, and the anhydrous begins to decompose and carbonize at 280°C. The relative density is 1.485 (25/4). Slightly soluble in cold water, insoluble in ethanol, ether and benzene, has significant acidity, soluble in caustic soda solution and sodium carbonate solution.

●  It is used in the manufacture of azo dyes, etc., and is also used as a pesticide to prevent and control wheat rust

●  Mainly used in the manufacture of dyes, printing and dyeing auxiliaries, prevention and treatment of wheat rust, and as intermediates for spices, food coloring, medicine, brighteners, pesticides, etc.

●  Used in organic synthesis, also used as chromatographic analysis reagents, etc.

●  Used as reference reagent, experimental reagent and chromatographic analysis reagent

●  Sulfanilicacidistoxic metabolite of Tartrazine (T007700).UsedasEhrlichreagent,fordetectingofnitrites.Antibacterial.

●  Determination of ammonia, cerium, and nitrite, determination of aluminum, magnesium, potassium, sodium, iodine, iodide and nitrite. Elemental analysis standards for carbon, hydrogen, nitrogen, oxygen and sulfur, used together with 1-naphthylamine for the determination of nitrite, for the detection of osmium and ruthenium, for the indirect determination of potassium through potassium nitrite, for the determination of serum bilirubin, for soil analysis.

●  It is derived from the reaction of aniline and sulfuric acid to form a salt and then transposition.
