Ninhydrin hydrate Chemical Properties,Uses,Production

Chemical Properties

White to pale yellow crystalline powder


Used for the detection of free amino groups in amino acids, peptides and proteins.


ChEBI: A member of the class of indanones that is indane-1,3-dione bearing two additional hydroxy substituents at position 2.

General Description

White to light yellow crystals or powder. Becomes anhydrous with reddening at 257-266°F.

Air & Water Reactions

Slightly soluble in water.

Reactivity Profile

Ninhydrin hydrate is sensitive to prolonged exposure to light. Ninhydrin hydrate yields highly fluorescent ternary compounds with aldehydes and primary amines.



Fire Hazard

Flash point data for Ninhydrin hydrate are not available. Ninhydrin hydrate is probably combustible.

Purification Methods

Crystallise ninhydrin from hot water (charcoal). Dry it under vacuum and store it in sealed brown containers. [Beilstein 7 IV 2786.]
