Mechanism When a free amino acid reacts chemically with ninhydrin, which acts as an oxidizing agent, its amino group undergoes oxidative deamination, leading to the production of CO2, NH3, an aldehyde, and a reduced form of ninhydrin known as hydrindantin. Subsequently, the ammonia released reac...

Role of hydrindantin in the determination of amino acids using ninhydrin. The mechanism of the reaction for quantitative determination of amino acids with ninhydrin has been extended to explain the dependence of color formation on hydrindantin concentration. Voltammetric techniques have been used to st...

The Mechanism of the New Ninhydrin Synthesis Diethyl phthalate condenses with methylsulfinyl carbanion to give 2-methylsulfinylindanedione-1,3. This new 尾-keto sulfoxide undergoes acid-catalyzed rearrangement reactions (Pummerer reactions) with various nucleophiles leading to 2-su... Becker,Hans-Dieter...
Ninhydrin is a nonspecific amino acid reagent in that it reacts in the same manner with different amino acids. In this way, each amino acid present in the latent fingermark deposit will contribute to the developed fingermark image. Amino acids are stable compounds that, due to an affinity ...

Imino acids, e.g. proline and hydroxyproline,react with ninhydrin to give a yellow color. At higher temperatures ("~100°C), the yellow compound (X) is trans- formed to the purple-red compound (XI) 1°. ... A mechanism for the formation of this compound can be easily written. ...
KINETIC STUDIES ON THE OXIDATION OF NINHYDRIN – AMINO ACID SYSTEMS USING ALKALINE PERMANGANATE The latter complex decomposes into products up on reacting with alkali in fast stage of the reaction. The reaction constants involved in the mechanism were derived. There is good agreement between the expe...
