Ninhydrin appears as white to light yellow crystals or powder. Becomes anhydrous with reddening at 257-266°F. (NTP, 1992)|Ninhydrin is a member of the class of indanones that is indane-1,3-dione bearing two additional hydroxy substituents at position 2. It has a role as a colour indicator and a human metabolite. It is a member of indanones, a beta-diketone, an aromatic ketone and a ketone hydrate.|2,2-Dihydroxy-1H-indene-1,3-(2H)-dione. Reagent toxic to skin and mucus membranes. It is used in chemical assay for peptide bonds, i.e., protein determinations and has radiosensitizing properties.Basic Info-
