Formula: C5H8N2. I found the field of Engineering; Materials Science; Mechanics very interesting. Saw the article Pyrazole ligands and their monometallic and bimetallic complexes: synthesis, characterization, and application as novel corrosion inhibitors published in 2020.0, Reprint Addresses Soltani, B (corresponding author), Azarbaijan Shahid Madani Univ, Dept Chem, Fac Sci, Tabriz, Iran.. The CAS is 67-51-6. Through research, I have a further understanding and discovery of 3,5-Dimethyl-1H-pyrazole.
A series of pyrazole ligands named as 1,4-bis(3,5-dimethylpyrazol-1-yl)butane (bbd), 1,3-bis(3,5-dimethylpyrazol-1-yl)propane (bdpp), and 1,3-bis(3,5-dimethylpyrazol-1-yl)propane-2-ol (bdpo) along with their transition metal complexes including [Cu-2(mu(3)-SCN)(2)(mu-bbd)](n), [Cu-2(mu(3)-SCN)(2)(mu-bdpp)](n), and [Cu2Hg(mu(2)-SCN)(2)(bdpo)(2)(CH3COO)(2)](n)were synthesized and characterized using FT-IR and Uv-vis spectroscopies, as well as thermal gravimetric analysis. The prepared compounds were investigated as corrosion inhibitors to protect mild steel in 0.5 M H(2)SO(4)solution. Corrosion tests were performed by electrochemical impedance spectroscopy and potentiodynamic polarization measurements. The pyrazole ligands exhibited inhibition efficiencies in a range of 38-78%, which introduced them as moderate inhibitors. On the other hand, the pyrazole complexes showed inhibition efficiencies higher than 85%, demonstrating their high potentials to mitigate the steel corrosion. In addition, the bimetallic complex resulted in higher corrosion resistance than the two monometallic complexes. This was evidence of a critical role of the coordinated metal of the complex in forming an adhesive protection film on the steel surface.
