MTN is the abbreviation for a chemical compound with the name 5-(methylthio)ninhydrin.
For example, ninhydrin can be sprayed onto the thin layer chromatography sheet,
In practice this amounts to about 4.5 gram ninhydrin crystals, 9 ml acetic acid, 18 ml of ethanol in 1 liter of Fluorisol.
Due to the sensitivity of ninhydrin hemiketals(like ThermaNin)
other techniques can be used afterwards e.g., the ninhydrin treatment of paper.
treated with DFO(left side) and ninhydrin(right side).
Introduction 5-MTN is the abbreviation for a chemical compound with the name 5-(methylthio)ninhydrin for the chemical structure see this pop-up window.
Yeah, well, I… I figured that the iodine would be more delicate than ninhydrin.
The strongly purple colored compound, that is formed when ninhydrin reacts with amino acids or proteins.
Japanese researchers have published that hemiketals of ninhydrin are soluble in petroleum ether(or other apolar solvents like pentane,
The strongly purple colored compound, that is formed when ninhydrin reacts with amino acids
did not develop fingerprints, where ninhydrin and DFO did.
which is white powder with good water-solubility, the ninhydrin reaction is positive.
The ninhydrin will not dissolve in petroleum ether,
Odén patented the use of ninhydrin and the use of a copper salt for fixing the prints in Great Britain and the USA[1b, 1c] despite the fact that it was widely known that in paper chromatography of amino acids and subsequent treatment with ninhydrin fingerprints would show when one wasn't careful in handling the paper.
So you used Ninhydrin?
The treatment of papers with the petroleum ether based ninhydrin working solution is not complicated.
DFO is a reagent that(like ninhydrin) reacts with the amino acids present in fingerprints.
We found that the hemiketal of 5-MTN with ethanol dissolves much faster than 5-MTN(ninhydrin) itself.
quick method to treat objects or papers with ninhydrin is the use of ninhydrin in an aerosol can.
