2,4-Dinitrophenylhydrazine (DNP) tests for aldehydes and ketones.
Must see: My new website at http://ww.acechemistry.co.uk. 2,4-DNP forms an orange ppt with aldehydes and ketone, the mp of which identifies the aldehyde or ketone that was reacted.

SOLVED:A precise diagnosis. The urine of an infant gives a positive reaction with 2,4 -dinitrophenylhydrazine. Mass spectrometry shows abnormally high blood levels of pyruvate, α-ketoglutarate, and the α-ketoacids of valine, isoleucine, and leucine. Identify a likely molecular defect and propose a definitive test of your diagnosis.
