Description

Buy High Quality Metanil Yellow (587-98-4) MF: C18H14N3O3S•Na | MW: 375.38. from Tristains.

Metanil Yellow is a vivid yellow to orange-yellow crystalline powder. It is also referred to as 3-(4-Anilinophenylazo)benzenesulfonic acid sodium salt, Acid Yellow 36, and is classified as a synthetic azo dye with the chemical formula C18H14N3NaO3S. This dye belongs to the azo dye group, which is distinguished by the presence of the azo (-N=N-) functional group. Its chemical composition comprises a benzene ring with a dimethylamino group, a sulfonate group, and an azo group. Metanil Yellow is soluble in water and alcohol, but insoluble in organic solvents. In the field of analytical chemistry, it serves as a pH indicator, undergoing a color transition from red to yellow within the pH range of 1.2 to 3.2.

Metanil yellow is an acid dye. Studies using cross-linked chitosan beads suggest that Metanil yellow has an adsorption capacity of 3.56 mmol g?1?at pH 4 and 30? C. Alternate studies indicate that photocatalytic degradation of Metanil yellow can be carried out using TiO2?as a photocatalyst under UV irradiation. In addition, ion chromatography of Metanil yellow displayed complete mineralization into CO2, N2, H2O and inorganic ions such as NH4+, NO3??and SO42-. Furthermore, Metanil yellow is useful in spectrophotometric methods to determine the presence of trace amounts of nitrates and nitrites in solution. The method utilizes the fact that potassium bromate can catalyze the discoloring of Metanil yellow which can then be analyzed by spectrophotometry.
