The author of 《Infrared spectra of pyrazoles. I. Monoalkyl-substituted pyrazoles》 were Zerbi, Giuseppe; Alberti, Carlo. And the article was published in Spectrochimica Acta in 1962. Recommanded Product: 52096-24-9 The author mentioned the following in the article:
The compounds studied were pyrazole, 3-alkyl-, 4-alkyl-, and N-alkylpyrazole, where the substituents were Me, Et, Pr, Bu, and amyl. The spectral region was 2-15 μ. Observed bands can be used to recognize the pyrazole structure and the position of the substituent. Most of the observed bands were assigned. In addition to this study using 1-Butyl-1H-pyrazole, there are many other studies that have used 1-Butyl-1H-pyrazole(cas: 52096-24-9Recommanded Product: 52096-24-9) was used in this study.
1-Butyl-1H-pyrazole(cas: 52096-24-9) belongs to pyrazoles. Pyrazoles and their related multiring analogs are common elements of a wide variety of bioactive compounds. These ring structures are rare in nature. A consequence of this is that they have previously been thought to be poor moieties to include in potential new drugs. Recommanded Product: 52096-24-9
