Pyrazole has a variety of physiological effects, including pain relief, anti-inflammatory, anti-fever, anti-arrhythmic, sedation, muscle relaxation, mental excitement, anti-spasm, monoamine oxidase inhibitor, anti-diabetic and anti-bacterial. Pyrazole can be used as an intermediate of certain medicines and pesticides, and it occupies a very important position in the research and development of medicines and pesticides. Pyrazole compounds have received more and more attention due to their wide spectrum of action and strong efficacy. In medical applications, pyrazole compounds have curative effects on many diseases; in pesticide applications, pyrazole compounds have insecticidal, bactericidal and herbicidal activities, and show high efficiency, low toxicity and structural diversity. Therefore, pyrazole drugs have broad research and development prospects. Pyrazole can also be used as the side chain of some photosensitive material monomers and has a wide range of applications. In addition, pyrazole is also used as a stabilizer for halogen-containing solvents, lubricating oils, chelating agents, and organic synthesis intermediates.
