Beschreibung

General description

Ninhydrin, a tricyclic 1,2,3-trione, is a useful organic building block.

Application

Zum Nachweis von freien Aminogruppen in Aminosäuren, Peptiden und Proteinen.

Ninhydrin (Triketohydrindene hydrate) may be used as a reagent for the quantification of amino acids and peptides by photometric method[1] and colorimetric method. It may be used to prepare the ninhydrin reagent, by mixing ninhydrin and hydrindantin (reduced form of ninhydrin) in dimethyl sulfoxide. This reagent is used in manual ninhydrin method for the quantitative determination of amino acids.[2]
