Ninhydrin (2,2-dihydroxyindane-1,3-dione) is an organic compound with the formula C 6 H 4 (CO) 2 C(OH) 2. It is used to detect ammonia and amines . Upon reaction with these amines, ninhydrin gets converted into deep blue or purple derivatives, which are called Ruhemann's purple.
Indane-1,2,3-trione is the organic compound with the formula C 6 H 4 (CO) 3.The compound is the dehydrated derivative of C 6 H 4 (CO) 2 C(OH) 2, known as ninhydrin, which is used to reveal fingerprints.
Documents that have been subjected to high levels of humidity will not generally retain indentations. As a result, other forensic examinations involving the wetting of a document, such as fingerprint development using a ninhydrin solution, should not be done until after examination for indentations. [14] Preparation
Ninhydrin (heating, amines and amino-acids) Acidic vanillin (heating, general reagent) Phosphomolybdic acid (no heating, general reagent) In the case of lipids, the chromatogram may be transferred to a polyvinylidene fluoride membrane and then subjected to further analysis, for example, mass spectrometry. This technique is known as far-eastern ...

Solution polymerization is a method of industrial polymerization. In this procedure, a monomer is dissolved in a non-reactive solvent that contains a catalyst or initiator . The reaction results in a polymer which is also soluble in the chosen solvent.
The solution? Moving All-Pro left guard Joe Thuney a few feet over to tackle helped plug that hole. It's one of the reasons the Chiefs have a chance to win a third straight Super Bowl on Sunday ...
