m-Toluidine, 4-(p-tolylazo)- - Introduction
Amino -4,2 '-azotoluene, also known as Yellow 3G, is an organic dye. The following is a description of its nature, use, preparation and safety information:
Nature:
Amino -4,2 '-azotoluene is a deep orange-yellow to red crystalline solid. It is insoluble in water and has some solubility in organic solvents. It has good stability and light resistance.
Use:
Amino -4,2 '-azotoluene is mainly used as a dye. It is commonly used to dye materials such as textiles, leather, paper and plastics to produce bright orange-yellow to red colors. In addition, it can also be used as an indicator in biochemical experiments.
Preparation Method:
The synthesis method of amino -4,2 '-azotoluene is generally obtained by the coupling reaction of dinitrotoluene and O-phenylenediamine. The specific steps include reacting dinitrotoluene and O-phenylenediamine together with a catalyst at a high temperature to generate the target product.
Safety Information:
Amino -4,2 '-azotoluene is generally relatively safe under typical use conditions. However, it is potentially irritating and allergenic. During use, care should be taken to avoid direct contact with skin, eyes and respiratory tract. In case of accidental contact, rinse immediately with water. For the environment exposed to it for a long time, there may be a potential risk of environmental pollution, so the relevant safety procedures should be followed when using and handling.
