Ninhydrine is the trade name of which of the following chemicals ?
Answer: B
Ninhydrin is triketohydrindene hydrate.
Ninhydrin (2,2-dihydroxyindane-1,3-dione) is the hydrate of indane-1,2,3-trione, traditionally named triketohydrindene hydrate. It reacts with amino acids in latent fingerprint residues on porous surfaces such as paper to give a purple product, Ruhemann's purple, and is one of the most widely used fingerprint reagents.
Hydroquinone is a photographic developer, the tetramethyl compound in the third option is not ninhydrin, and osmium tetroxide (printed 'trioxide') is a fuming reagent of a different kind.
