Ninhydrin (2,2-dihydroxyindane-1,3-dione) is an organic compound with the formula C 6 H 4 (CO) 2 C(OH) 2. It is used to detect ammonia and amines . Upon reaction with these amines, ninhydrin gets converted into deep blue or purple derivatives, which are called Ruhemann's purple.
Indane-1,2,3-trione is the organic compound with the formula C 6 H 4 (CO) 3.The compound is the dehydrated derivative of C 6 H 4 (CO) 2 C(OH) 2, known as ninhydrin, which is used to reveal fingerprints.
Schiff bases have been investigated in relation to a wide range of contexts, including antimicrobial, antiviral and anticancer activity. They have also been considered for the inhibition of amyloid-β aggregation.

1-Fluoro-2,4-dinitrobenzene (commonly called Sanger's reagent, dinitrofluorobenzene, DNFB or FDNB) is a chemical that reacts with the N-terminal amino acid of polypeptides. This can be helpful for sequencing proteins.
Product of the xanthoproteic reaction with the characteristic yellow color. The xanthoproteic reaction is a method that can be used to detect a presence of protein soluble in a solution, using concentrated nitric acid.
Hawkinsin is ninhydrin positive (a common test to detect amino acids and proteins with a free -NH 2 group). It is found in elevated concentrations in the urine in hawkinsinuria, which is probably related to the depletion of glutathione and resulting high excretion of 5-oxoproline. [2]
The older ninhydrin method, which is a liquid that is sprayed on paper to detect latent prints on paper is similar. The FBI were able to raise two prints which they photographed promptly because, unlike modern polycyanoacrylate, fuming prints revealed by the iodine process fade quickly.
