Function:
Alkalinity and salt-forming property: The amino group in the molecule makes it alkaline to a certain extent, and it can react with acid to form salt, such as reacting with hydrochloric acid to form monohydrochloride. This salt-forming property can improve its solubility and stability in water, making it easier to use in different solvent systems.
Application:
Developer: It can be used as a developer in the development process of black and white photography. It can reduce the exposed silver halide crystals to metallic silver, thereby converting the latent image into a visible image. It has a certain development speed and contrast adjustment ability, and the formula can be adjusted according to different photographic needs.
Chemical analysis reagent: It can be used for the detection and analysis of certain metal ions.
