Pyrazoles can be selectively lithiated at different carbons and subsequently react with electrophiles depending on the substitution patterns. 2075-46-9, formula is C3H3N3O2, Name is 4-Nitro-1H-pyrazole. 1-Methyl-5-(trifluoromethyl)pyrazole underwent deprotonation and subsequent carboxylation mainly or exclusively at either the 4-position of the heterocycle or at the nitrogen-attached methyl group.

Nagai, Yuki;Ishiba, Keita;Yamamoto, Ryosuke;Yamada, Teppei;Morikawa, Masa-aki;Kimizuka, Nobuo research published \u300a Light-Triggered, Non-Centrosymmetric Self-Assembly of Aqueous Arylazopyrazoles at the Air-Water Interface and Switching of Second-Harmonic Generation\u300b, the research content is summarized as follows. Trans-p-methoxy arylazopyrazole spontaneously forms non-centrosym. polar crystals, which reversibly undergo liquefaction upon photoisomerization to the cis-isomer. This liquid cis-isomer has a large elec. dipole moment and is highly soluble in water (solubility up to \u224858 mM), which is remarkably higher than that of the trans-isomer (690 \u03bcM). Vis-light illumination of the aqueous cis-isomer generates macroscopically oriented, non-centrosym. crystals at the air-water interface. Polar crystals are also formed in sandwich glass cells (spacing, 20 \u03bcm) upon photo-induced crystallization of the liquid cis-isomer. The trans-crystals thus formed showed second harmonic generation (SHG) whose intensity is switched on\/off in response to the photo-induced phase transition.<\/p>\n

SDS of cas: 2075-46-9<\/a>, 4-Nitro-1H-pyrazole, also known as 4-Nitropyrazole, is a useful research compound. Its molecular formula is C3H3N3O2 and its molecular weight is 113.08 g\/mol. The purity is usually 95%.<\/p>\n

4-Nitropyrazole, is a building block for the synthesis of various pharmaceutical compounds, including inhibitors, and therapeutic agents. It can be used for the synthesis of highly selective, brain-penetrant aminopyrazole LRRK2 Inhibitor, as a potentially viable treatment for Parkinson’s disease., 2075-46-9.<\/p>\n
