Abstract

Four hitherto unknown amino derivatives of ninhydrin have been prepared and examined as potential fingerprint reagents. All gave intensive colors upon reaction with amino acids in solution and developed latent fingerprints on paper in a manner similar to ninhydrin. The 5-substituted derivatives, 5-aminoninhydrin and 5-dimethylaminoninhydrin, also exhibited direct fluorogenic activity with amino acids and with latent fingerprints. Addition of Group IIb metal salts had no marked effect on the fluorogenic process.
