Description:
Ninhydrin hydrin is a pale yellow crystalline powder with 1 molecular crystal water, with a melting point of 241-243℃ (water loss and reddening at 125-130℃). Soluble in alcohol, water, slightly soluble in ether and chloroform. See light or dew place gradual discoloration in air, can absorb moisture agglomerate.
Methods: diethyl phthalate and ethyl acetate were reacted in the presence of sodium metal to form ethyl benzoglutarone formate.
It is used for the determination of amino acids, peptides and proteins. For the detection and analysis of peptides, amino acids, amines and amino sugars, it can produce high-fluorescence ternary compounds with aldehydes and primary amines.
