Nomenclature of Hydrazone 7 formation

The nomenclature of Hydrazone 7 follows the IUPAC naming conventions for hydrazones. The name of Hydrazone 7 can be derived from the names of the two hydrazine derivatives used in its synthesis, namely, 2-pyridylhydrazine and 2,4-dinitrophenylhydrazine. The naming convention for hydrazones involves naming the two substituents attached to the carbonyl group and adding the suffix “-hydrazone” at the end.

Therefore, Hydrazone 7 can be named as 2-(pyridin-2-yl)hydrazono)-2,4-dinitrophenol or 2-pyridyl-N’-[2,4-dinitrophenyl] hydrazone, depending on the preference of the nomenclature system used.

The IUPAC name for 2-pyridylhydrazine is pyridin-2-ylhydrazine, and the IUPAC name for 2,4-dinitrophenylhydrazine is 1-(2,4-dinitrophenyl) hydrazine.

Here is a hypothetical case study on the synthesis and application of Hydrazone 7:

Dr. Sarah, a medicinal chemist, is working on developing new compounds for the treatment of Alzheimer’s disease. She hypothesizes that a series of hydrazones could be promising candidates for drug development due to their potential ability to inhibit the acetylcholinesterase enzyme, which is involved in the breakdown of acetylcholine, a neurotransmitter associated with memory and learning.

Dr. Sarah decides to synthesize Hydrazone 7 and test its inhibitory activity against acetylcholinesterase.
