3-Methyl-4-nitro-1H-pyrazole (cas: 5334-39-4) belongs to pyrazole derivatives. Pyrazole is a weak base, with pKb 11.5 (pKa of the conjugated acid 2.49 at 25 °C).Pyrazole used as a ligand to prepare organometallic compounds. Pyrazoles are commonly used scaffold molecules in drug discovery projects. The use of pyrazole derivatives is based on their analgesic, anti-inflammatory, antipyretic, antiarrhythmic, sedative, muscle relaxant, neuroleptic, anticonvulsant, monoamine oxidase inhibitory, antidiabetic and antibacterial activities.Reference of 5334-39-4

Adamantylazoles. IV. Acid-catalyzed adamantylation of pyrazoles was written by Gavrilov, A. S.;Golod, E. L.;Kachala, V. V.;Ugrak, B. I.. And the article was included in Russian Journal of Organic Chemistry (Translation of Zhurnal Organicheskoi Khimii) in 2001.Reference of 5334-39-4 This article mentions the following:

Pyrazoles with pKBH+ no more than 0.8 and having substituents in the 3(5) position with effective van der Waals radii not exceeding 2 Å in a mixture of phosphoric and acetic acids at weight ratio 4:1 (H0 -1.8) react with 1-adamantanol to afford 1-(1-adamantyl)- or 1,4-di-1-adamantylpyrazoles. In the experiment, the researchers used many compounds, for example, 3-Methyl-4-nitro-1H-pyrazole (cas: 5334-39-4Reference of 5334-39-4).
