Brady’s test for aldehydes and ketones
Source: © Shutterstock
Identify aldehydes and ketones using Brady’s reagent (2,4-dinitrophenylhydrazine) in this microscale experiment. Includes kit list and safety instructions.
In this practical, students add various liquid aldehydes and ketones to 2,4-dinitrophenylhydrazine solution in a well-plate or spotting tile to form solid derivatives. They then do the same test with methanol and ethanol, showing that the reaction does not occur with alcohols.
