4-Chloro-3,5-dimethyl-1H-pyrazole (cas: 15953-73-8) belongs to pyrazole derivatives. An alternative way to synthesize multisubstituted pyrazoles is the Csingle bondH arylation of simple pyrazoles. 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.Recommanded Product: 15953-73-8

The ultraviolet absorption spectra of pyrazoles and 1-carboxamidepyrazoles and their application was written by Shi, Yun-feng;Wu, Zhi-jie;Chen, Li-jun;Chen, Guang;Liu, Yao-peng;Zhang, Li-li. And the article was included in Guangpuxue Yu Guangpu Fenxi in 2009.Recommanded Product: 15953-73-8 This article mentions the following:

The UV absorption spectra of pyrazoles and 1-carboxamidepyrazoles were studied. The results indicated that substitution in the 3 or the 5 position it leads to a bathochromic shift of the position of the maximum absorption by about 3-4 nm, whereas in the 4 position leads to a much larger bathochromic shift (>10 nm). The introduction of carboxamide causes a bathochromic shift of the position of the maximum absorption by about 20-26 nm. Its also leads to an increase in molar extinction coefficient by about 2-3 times. So UV methods were established for determining the contents of pyrazoles and their derivations. Using these methods. the content of 3,4-dimethylpyrazole phosphate (DMPP) in stabilized urea was determined to be 1.15% of urea-N, the hydrolytic half lives of 1-carboxamide-3-methylpyrazole (CMP) in water solution at 20°, 25°, and 30° were 48, 30, and 16 h, resp., and the extraction percentage of nitrification inhibitor 3-methylpyrazole phosphate (MPP) in 3 soils by 3 different extractants were ranged from 63.2% to 89.2%. In the experiment, the researchers used many compounds, for example, 4-Chloro-3,5-dimethyl-1H-pyrazole (cas: 15953-73-8Recommanded Product: 15953-73-8).
