Direct Red 31 is a dye that functions as a colorant in experimental applications. It interacts with the molecular structure of the material it is applied to, forming strong covalent bonds with the substrate. This chemical has the ability to bind to specific sites on the material, resulting in a permanent color change. Direct Red 31 achieves this by undergoing a series of chemical reactions with the substrate, leading to the formation of stable, colored complexes. Its mode of action involves the formation of these complexes through a process of electron transfer and bonding, resulting in a vivid and long-lasting coloration of the material.
