How is ninhydrine reagent prepared?
100mls of N-butyl, 3mls of glacial Acetic acid and 1.5grams of Ninhydrin.
Why you will spray ninhydrin for analysis in chromatography?
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).
What chemical reagent of protein?
Biuret reagent is used to test for protein in urine. It is a common test that students in biology class perform. Urine is added to a test tube, followed by approximately the same amount of Biuret reagent. If the solution turns lavender this means that there are proteins present in the urine.
How Benedict's reagent solution react with potato juice?

Why do all monosaccharide react with Benedict's reagent?
because know one cares
Why egg albumin and casein did not react ninhydrin reagent?
It should react to this reagent. However it must be HEATED before it will react.This is due to the fact that when Ninhydrin is heated it stabilizes and the reacts with the -NH2 groups on the amino acid.
What is the spraying reagent used for citric acid paper chromatography?
ninhydrin reagent
What is the molecular formula of ninhydrin?
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
