Xylidyl Blue II - Introduction

Magon is an organic dye, also known as Acid Blue 6. Its chemical formula is C15H16N3O2S, and its molecular structure contains methylaniline and phenylamine groups.

Magon is a blue powder with good solubility and dyeing properties. It is usually used as an acid dye, which can dye textiles, leather, paper and other materials under acidic pH conditions. The dye appears dark blue in solution, but its color can change with a change in pH.

Magon is generally prepared by reacting dimethylaniline with carbon disulfide under alkaline conditions. The reaction was carried out by first dissolving dimethylaniline in water, then adding an alkaline solution to adjust the pH, and finally adding carbon disulfide. After completion of the reaction, the pure product was obtained by evaporation of the solvent and crystal separation.

Regarding safety information, Magon's contact should be careful to prevent swallowing
