Product Description Ninhydrin (2,2-dihydroxyindane-1,3-dione) is an organic compound with the formula C6H4(CO)2C(OH)2. It is used to detect am monia and amines. Upon reaction with these amines, ninhydrin gets converted into deep blue or purple derivatives, which are called Ruhemann's purple. Ninhydrin is most commonly used to detect fingerprints in forensic cases, as the terminal amines of lysine residues in peptides and proteins sloughed off in fingerprints react with ninhydrin.Ninhydrin is a white solid that is soluble in ethanol and ace tone.Ninhydrin can be considered as the hydrate of indane-1,2,3-trione.TEST ITEMSSTANDARDRESULTSPHYSICAL APPEARANCESLIGHT YELLOWISH CRYSTALLINE POWDERCOMPLIESMELTING POINT250-253oC250-253oC(WITH DECOMPOSITION)PASSES TESTPH OF 1% SOLUTION4.0-5.54.0 to 5.54.5MOISTURE CONTENT9-11%9 to 11%9.80%SOLUBILITY0.1GM IN 10ML WATER(CLEAR PALE YELLOW SOLUTION)PASSES TESTASSAY ON ANHYDROUS BASIS98.0%99.5%
