Ninhydrin, like everything out is safe when used properly. If you spill it on your skin it may cause irritation. If it touches your skin you should wash it throuoghly with soap and water. Remove any clothing that it touches and wash immediately before reuse.
If it comes into contact with your eye you need to wash it throughly for a minimum of 15 whiles while contacting medical attention via the emergency phone system for your country (e.g. 999, 911, 112).

Is ninhydrin the same as super glue?
NO, ninhydrin is not the same as super glue
Does ninhydrin has flaws?
Yes ninhydrin does have flaws. The most common flaw of ninhydrin is the fact that it is so sensitive to the extent of not recording a fingerprint if enough perspiration wasn't created.
Is Ninhydrin used to test for the presence of lipids?
No, a grease spot test or Sudan IV test can be used to test for lipids. Ninhydrin is used to test for amino acids.
What is ruhemanns purple formed in ninhydrin reaction?
It is the final coloured compound.
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 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
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).
Result of casein in ninhydrin test?
Kharkov's
Would ninhydrin test be reliable in determining the presence of proteins?
No! because the Ninhydrin test is mostly used to detect ammonia or primary secondary amines
Is Ninhydrin used to test for the presence of lipids?
No, a grease spot test or Sudan IV test can be used to test for lipids. Ninhydrin is used to test for amino acids.

What is the spraying reagent used for citric acid paper chromatography?
ninhydrin reagent
How do you estimate proline?
Ninhydrin reacts with proline to give a red colored product
