Application
可以用于检测氨基酸，多肽和蛋白质中的自由氨基基团。
Ninhydrin (triketohydrindene hydrate) may be used as reagent for the quantification of amino acids and peptides by photometric method 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.
