What is the name of the final colored compound produced through the treatment of Ninhydrin?

The final colored compound produced through the treatment of Ninhydrin is known as Ruhemann's Purple. This compound is a result of the reaction between Ninhydrin and amino acids, which are commonly found in fingerprint residues. When Ninhydrin interacts with these amino acids, it undergoes a chemical transformation that results in the formation of Ruhemann's Purple, characterized by its distinct purple hue. This color change is significant for latent print examination, as it aids in visualizing fingerprints that may not be otherwise discernible on various surfaces.

The implication of using Ruhemann's Purple in forensic science is profound, as it enhances the contrast of the latent print against the background, allowing for more effective identification and analysis of the prints collected at crime scenes.
