Pyrazole (CAS: 288-13-1) is a heterocyclic crystalline aromatic compound with a five-membered ring containing three carbon atoms and two nitrogen atoms. Pyrazole is a versatile building block, with a vast applications in organic synthesis. The derivatives of Pyrazole are used in medicine, for their analgesic, anti-inflammatory, antipyretic, antiarrhythmic, tranquilizing, muscle relaxing, psychoanaleptic, anticonvulsant, monoamineoxidase inhibiting, antidiabetic and antibacterial activities. 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. 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 halogen-containing solvent, a stabilizer for lubricating oil, a chelating agent, and an intermediate for organic synthesis. Pyrazole is used in organic synthesis and as a chelating agent. Used as a ligand to prepare organometallic compounds. Hazard: Toxic by ingestion and inhalation, irritant to skin and eyes.
