Ninhydrin is a chemical used to expose latent fingerprints, but its use is declining because of the slow reaction time it takes for it to react with the oil in the fingerprints. You can use heat to speed the process up but there are other faster options.

No, although questions as to her virginity before Henry have always been raised.
Well, the best I could come up with is it's either:C9H6O2orC4H3O2If someone knows any different please correct me.jman63: it is actually C9H6O4
Yes, ninhydrin has some drawbacks. It can react with other substances present in the sample, leading to false positive results. Additionally, the reaction with ninhydrin is not specific to a particular amino acid, which can limit its application in identifying specific amino acids.

NO, ninhydrin is not the same as super glue
The boiling point of ninhydrin is approximately 275-280°C.
Ninhydrin reagent is prepared by dissolving ninhydrin powder in a solvent such as ethanol or acetone. The solution is typically heated gently to aid dissolution. It is important to prepare fresh ninhydrin reagent before use to ensure its effectiveness in detecting amino acids.
Since amino acids are colourless compounds, ninhydrin is used for detecting them. To identify this, after development, the TLC plate is sprayed with ninhydrin reagent and dried in an oven, at 105°C for about 5 minutes. Ninhydrin reacts with α- amino acids that results in purple coloured spots [(due to the formation of the complex - Rheuman's purple).
No! because the Ninhydrin test is mostly used to detect ammonia or primary secondary amines

When ammonia or primary and secondary amines are detected, a deep blue or purple color known as Ruhemann's purple is produced. Ninhydrin can also be used to monitor deprotection in solid phase peptide synthesis (Kaiser Test). The chain is linked via its C-terminus to the solid support, with the N-terminus extending off it. When that nitrogen is deprotected, a ninhydrin test yields blue. Amino-acid residues are attached with their N-terminus protected, so if the next residue has been successfully coupled onto the chain, the test gives a colorless or yellow result.
