Test For The Presence Of Aldehydes And Ketones (2,4-DNPH reagent)
@learnchemi First to test for the presence of aldehydes and ketones we can use 2,4-dinitrophenylhydrazine (often abbreviated to 2,4-DNPH). When 2,4-dinitrophenylhydrazine or 2,4-DNPH (orange color) is added to any aldehyde or ketone the 2,4-DNPH red or deep orange precipitate of 2,4- Dinitrophenylhydrazone is formed. If the precipitate is dried ...
