Polymerization of DFP2kwith hydrazine Aldehyde can react with hydrazine under mild reaction conditions Conclusions In summary, a novel AIE polymer PDFP2kwas synthesized via the aldehyde-hydrazine step polymerization. Due to the hydrophilic PEG segments and hydrophobic SA moieties, the polymer is amphiphil...
, yogurt, cheeses, and red wines). However, such reactions have not been reported. Concomitant use of narcotics or other strong sedatives may result in exaggerated depressant effects, leading to coma and possibly death. Procarbazine also interacts with alcohol, causing a disulfiram-like reaction....
The universal character of solubilization by the cationic surfactant micelles in the aromatic aldehyde鈥 2,4-dinitrophenylhydrazine systems was shown by an example of the benzaldehyde derivatives with substituents of different nature. This effect leads to the increase in solubility of the reaction ...

dextran polyaldehydedetermination of the number of aldehydesA method for determining the number of aldehydes in dextran polyaldehyde (DPA) was proposed. The method was based on the production of the DPAconjugate with 2,4-dinitrophenylhydrazine, reaction of which with base formed a colored product....
example of a suitable organic base which can be used. Any deprotection at R20which is required after the reaction can be carried out in a known manner depending on the nature of the protecting group present. For example, phthalimido can be converted into amino by treatment with hydrazine ...
