manufacture starting materials 1,3-Indanedione and
1,3-Indanedione oxime required for Ninhydrin.
Ninhydrin
(2,2-Dihydroxyindane-1,3-dione) is a chemical used to detect
ammonia or primary and
secondary
amines.
When reacting with these free amines, a deep blue or purple
color known as Ruhemann's purple is evolved.
Ninhydrin is most commonly used to
detect
fingerprints.
Ninhydrin is a stable hydrate form of its parent carbonyl
compound (1,2,3-Indanetrione)

Reactivity
Uses
A ninhydrin solution is commonly used by
forensic investigators in the analysis of latent
fingerprints on porous surfaces such as paper.
Amino acid containing finger marks, formed by
minute sweat secretions which gather on the
finger's unique ridges, are treated with the
ninhydrin solution which turns the amino acid
finger ridge patterns purple and therefore
visible.
The carbon atom of a carbonyl
bears a partial positive charge, so the central carbon of a
1,2,3-tricarbonyl is less stable and more electrophilic than a
simple ketone. In most compounds, a carbonyl is more stable than
the dihydroxy (hydrate) form. However, ninhydrin is a stable
hydrate of the central carbon because this form does not have
the destabilizing effect of adjacent carbonyl partial-positive
centers. Indane-1,2,3-trione reacts readily with nucleophiles.
Ninhydrin is widely used in the
analytical chemistry as a reagent for detecting various substances
by TLC. Spraying the TLC patterns with ninhydrin reveals the spot of
∞-amino Acids, peptides, ephedrine and pseudoepedrine hydrochloride,
caffeine, theophylline, morphine hydrochloride, gentamicin sulfate,
neomycin, Gamma-aminobutyric acid, tauphon and many other
