Solvent Red 132, whose chemical name is 1-[(2,4-dimethylnitroso) methyl] benzene (2-nitrophenyl) amine, is an organic synthetic dye. The following is a description of the nature, use, formulation and safety information of Solvent Red 132:
Nature:
-Appearance: Solvent Red 132 as red powder or crystal.
-Solubility: Soluble in organic solvents such as alcohols and esters, insoluble in water.
Use:
- Solvent Red 132 as a dye is widely used in the coloring of textiles, plastics, inks, dye oils, pigments and other industrial products.
-In the laboratory, Solvent Red 132 can also be used as an indicator, such as an acid-base indicator in acid-base titration.
Preparation Method:
- Solvent Red 132 can be obtained by reacting aniline with 2,4-dinitromethane. First, in the presence of hydrogen, aniline reacts with nitrous acid to form nitrosoaniline. Nitrosoaniline then reacts with 2,4-dinitromethane to form the Solvent Red 132.
Safety Information:
- Solvent Red 132 is considered to be a dye safe for humans and the environment under general conditions.
-However, like all chemical substances, use should be in accordance with safe handling guidelines and avoid swallowing or contact with skin, eyes and respiratory tract.
