It is slightly soluble in water (2.5 g/L) according to RÖMPP chemical encyclopedia. https://roempp.thieme.de/lexicon/RD-04-01816

Hello.

It is very slightly soluble in water. If you are planning to use it for biological studies, it won't work.

Dear all, please have a look at the following RG thread. Would you please tell why the solubility in water is needed? My Regards

Dear Shubang Vyas as already mentioned in the previous expert answers, the solubility of 2,4-dinitrophenylhydrazine in water is very low (almost negligible). Commonly, reactions with 2,4-dinitrophenylhydrazine (e.g. for the characterization of aldehydes and ketones as 2,4-dinitrophenylhydrazones) are carried out in ethanolic solution. A particularly good solvent for 2,4-dinitrophenylhydrazine is diglyme (= bis(2-methoxyethyl) ether).

Good luck with your experiments and best wishes, Frank Edelmann

It is very slightly low in water (almost negligible), so I recommend using an ethanolic solution.
