1-Phenyl-4,5,6,7-tetrahydro-1H-pyrazolo[4,3-c]pyridine

The chemical structure of 1-phenyl-4,5,6,7-tetrahydro-1H-pyrazolo [4,3-c] pyridine can be deduced as follows. "1-phenyl" means that in the molecular structure, there is a phenyl group attached to the main structure. The phenyl group is the remaining group after the benzene ring is removed from a hydrogen atom. It has a cyclic structure composed of six carbon atoms and has a conjugated double bond on the ring, which is stable and aromatic.
The term "4,5,6,7-tetrahydro" means that on the carbon atoms at positions 4, 5, 6, and 7 of the main structure, the original double bond is converted into a single bond by hydrogenation reaction, and hydrogen atoms are added. This change results in a decrease in the degree of unsaturation of the main structure.
"1H-pyrazolo [4,3-c] pyridine" part, the structure of pyrazolo-pyridine is formed by fusing the pyrazole ring with the pyridine ring. Pyrazole ring is a five-membered heterocycle containing two adjacent nitrogen atoms, which has certain aromatic properties. Pyridine ring is a six-membered heterocycle containing one nitrogen atom, which is also aromatic. The way of fusing the two is [4,3-c], that is, according to the specific atomic connection rules, the pyrazole ring and the pyridine ring combine to form a unique fused ring structure. 1H represents the hydrogen atom in the first position. This hydrogen atom occupies a specific position in the whole molecular structure, which affects the chemical properties and reactivity of the molecule.
In summary, the chemical structure of 1-phenyl-4,5,6,7-tetrahydro-1H-pyrazolo [4,3-c] pyridine is a complex organic compound with a pyrazolo-pyridine fused ring as the backbone, 4, 5, 6, and 7 positions are hydrogenated, and 1 position is connected with a hydrogen atom, and at a specific position is connected with a phenyl group.
