Vibrational and theoretical analysis of pentyl-4-benzoyl-1-[2,4-dinitrophenyl]-5-phenyl-1H-pyrazole-3-carboxylate

A Novel Electrochemical Sensor for Detection of Baicalein in Human Serum Based on DUT‐9/Mesoporous Carbon Composite

“…The peak at 1398 cm −1 is due to the anti‐symmetrical vibration of COO ‐ grouping . And the peaks of 1604, 1554 cm −1 belong to the C=C in the benzene ring . The bands at 857, 782, 706, and 667 cm −1 correspond to the C−H in the benzene ring .…”

Silver‐catalyzed Regioselective Synthesis of N‐aryl‐1H‐pyrazolyl‐substituted Benzenesulfonamides from Ynamides and Pyrazoles

“…Several natural products, agrochemicals, and pharmaceuticals contain heterocyclic nitrogen‐containing substrates [1] . As a class of nitrogen‐containing five‐membered heterocycles, pyrazoles are characterized by the presence of an important structural motif that explains their wide‐ranging use in pharmaceutical, [2] chemical, [3] and agrochemical industries [4] …”

“…[1] As a class of nitrogen-containing five-membered heterocycles, pyrazoles are characterized by the presence of an important structural motif that explains their wide-ranging use in pharmaceutical, [2] chemical, [3] and agrochemical industries. [4] There have been many pyrazole derivatives produced for various medicinal purposes including antidepressants, anticonvulsants, [5] antituberculars, [6] antitumors, [7] antagonists of GABA receptors, insecticides, [8] anticancers, [9] antipyretics, [10] anti-inflammatory agents, and antimicrobials. [11] Some of the most potent derivatives of pyrazoles are depicted below (Figure 1).…”
