Monomethy-p-aminophelol sulfate, one of two developing agents used in radiographic developing solutions. Its primary function is to act quickly to bring out the shades of gray in a radiographic image.
One component of the developing agent plays a crucial role in the initial phases of development and contributes to generating the fundamental grayscale image of a radiograph. Additionally, within the developer agent, hydroquinone is another constituent that exhibits a comparatively slower rate of action when compared to metol.
