The reaction of ninhydrin with primary amino groups to form the purple dye now called Ruhemann's purple (RP) was discovered by Siegfried Ruhemann in 1910. In addition, imines such as pipecolic acid and proline, the guanidino group of arginine, the amide groups of asparagine, the indole ring...
Ninhydrin hydrate Reaction Ninhydrin, also known as Ninhydrin hydrate, is a chemical used to detect potential fingerprints on porous surfaces such as paper and cardboard. This compound reacts with the amino acid (eccrine) component of the fingerprint deposit to produce a dark purple product known...

The sensitivity of the ninhydrin reaction is up to 0.01 percent. Modern automatic amino-acid analysis is carried out by combining the ion-exchange separation of amino acids and their quantitative identification using the ninhydrin reaction. The reaction is also used to detect each type of amino aci...
