a-(2 ,4-Dichlorophenyl)-2 -{ 1 H-imidazole-1-yl )ethanol

This compound is named a- (2,4-dihydroxyphenyl) -2- {1H-pyrazole-1-yl} ethanol, and its chemical structure is as follows: First, there is a basic skeleton of ethanol, namely -CH 2O CH 2O OH structure. In the alpha position of ethanol (the carbon atom attached to the hydroxyl group), a benzene ring is connected, and the 2,4 positions of this benzene ring are respectively replaced by hydroxyl groups (-OH) to form a 2,4-dihydroxyphenyl structure. At the same time, the α-position of ethanol is also connected to a 1H-pyrazole-1-group. 1H-pyrazole is a five-membered heterocyclic ring containing two nitrogen atoms. 1-group means that the atom connected to the 1-position of the pyrazole ring is connected to the carbon atom of the α-position of ethanol. Thus, the chemical structure of a- (2,4-dihydroxyphenyl) -2-{ 1H-pyrazole-1-yl} ethanol is formed.
