Widely used as a developing agent in black and white photographic developers, especially in low-temperature and high-speed processing. It offers excellent activity at lower temperatures, making it suitable for use in automatic processing systems where chemical performance must remain consistent under varying conditions. Dimezone S is often combined with other developing agents like Phenidone to create synergistic effects, enhancing image sharpness and reducing development time. It is favored in some formulations for producing fine grain and high image quality, particularly in motion picture and technical films. Its stability in alkaline solutions also contributes to longer developer shelf life and consistent performance.
