Glycin, or N-(4-hydroxyphenyl)glycine, is N-substituted p-aminophenol. It is a photographic developing agent used in classic black-and-white developer solutions. It is unrelated to the amino acid glycine. When fresh, it is typically characterized as thin plates of white or silvery powder, turning brown with age. It is sparingly soluble in water and most organic solvents; it is readily soluble in alkalies and acids.
