From the modern uses of Sulphanilic Acid, the production of colourings for textile and food industry stands out, as well as optic whiteners for paper and detergents manufacture.
What is Sulphanilic Acid formula?
C6H7NO3S
Sulfanilic acid/Formula
What type of ion is sulfanilic acid?
Sulphanilic acid is a dipolar ion and exists as cation in acidic medium and as an anion in basic medium.
How is sulfanilic acid made?
Reflecting its wide use, sulfanilic acid is found in the leachates of landfills. It is produced by reduction of some azo dyes.
What is diazotized sulfanilic acid?
Diazotized sulfanilic acid as a novel reagent for the detection of phenothiazine, phenothiazine-like drugs and their decomposition products in pharmaceuticals. Pharmazie.
What is the density of sulfanilic acid?
1.48 g/cm³
Sulfanilic acid/Density
Which method is diazotized sulfanilic acid used?
Van den Bergh chemical reaction
The Van den Bergh chemical reaction which is used to measure bilirubin levels, couples bilirubin with diazotized sulfanilic acid. This reaction produced azo pigments, or azobilirubin. The presence of azobilirubin is best indicated by the emergence of a pink-purple color.
What does Diazotized mean?
Definition of diazotize transitive verb. : to convert (a compound) into a diazo compound (such as a diazonium salt)
What is the molecular weight of sulfanilic acid?
173.2 g/mol
Sulfanilic acid/Molar mass
What is the principle of the bilirubin and sulfanilic acid reaction?
PRINCIPLE. Bilirubin will react with diazotized sulfanilic acid to yield a purple compound, azobilirubin. This product can be quantitated spectrophotometrically at 560 nm.
How is aniline Diazotized?
Much like in primary aliphatic amines, aminobenzene (aniline) is converted into a diazonium ion by treating it with a nitrous acid and mineral acid mixture. Formally, a nitrosyl cation ( N O + ) is then transferred to the amine.
What is the Jendrassik Grof method?
The DxC800 uses a timed-endpoint Diazo method (Jendrassik-Grof) to measure the concentration of total bilirubin in serum or plasma. In the reaction, bilirubin reacts with diazo reagent in the presence of caffeine, benzoate, and acetate as accelerators to form azobilirubin.
What is the structure of sulfanilic acid?
Sulfanilic acid ( 4-aminobenzenesulfonic acid) is an organic compound with the formula H 3 NC 6 H 4 SO 3. It is an off-white solid. It is a zwitterion, which explains its high melting point. It is a common building block in organic chemistry.
Sulfanilic acid (4-aminobenzenesulfonic acid ) is an off-white crystalline solid which finds application in quantitative analysis of nitrate and nitrite ions. The solid acid exists as a zwitterion, and has an unusually high melting point.
What is the use of NNN-(1-Naphthyl)ethylenediamine dihydrochloride?
N-(1-Naphthyl)ethylenediamine dihydrochloride is widely used in the quantitative analysis of nitrate and nitrite in water samples by colorimetry. It readily undergoes a diazonium coupling reaction in the presence of nitrite to give a strongly colored azo compound.
How do you remove sulfanilic acid from the air?
Particulate-phase sulfanilic acid may be removed from the air by wet or dry deposition. Sulfanilic acid absorbs UV light at wavelengths >290 nm, and therefore susceptible to direct photolysis by sunlight. If released to soil, sulfanilic acid is expected to have very high mobility based upon an estimated Koc of 10.
