/ˌnɪnˈhaɪdrɪn/

Origin: A borrowing from German. Etymon: German Ninhydrin.

Etymology: < German Ninhydrin (proprietary name: see quot. 1912), probably partially < the chemical name, in English triketohydrindene.

Chemistry.

A brown crystalline bicyclic compound, C₉H₆O₄, which forms deeply coloured products with amines and is particularly used for detecting and estimating amino acids; triketohydrindene hydrate; 1,2,3-indantrione hydrate. Frequently attributive.
