Properties: It is a bright red powdered solid, soluble in some organic solvents such as ethanol, but insoluble in water. It shows good stability under both acidic and alkaline conditions.
Use: Solvent red 1 is commonly used as a chemical indicator, which can be used in chemical experiments such as acid-base titration and metal ion determination. It can be yellow in an acidic solution and red in an alkaline solution, and can indicate the pH of the solution through the change in color.
Preparation method: The preparation method of solvent red 1 is relatively simple, generally synthesized by condensation reaction of nitroaniline and p-aminobenzophenone. The specific synthesis method can be carried out in the laboratory.
