Pyrazole is an organic compound with the formula C3H3N2H. It is a heterocycle characterized by a 5-membered ring of three carbon atoms and two adjacent nitrogen atoms, which are in ortho-substitution. 2075-46-9, formula is C3H3N3O2, Name is 4-Nitro-1H-pyrazole. Pyrazoles are a class of compounds that have the ring C3N2 with adjacent nitrogen atoms.Notable drugs containing a pyrazole ring are celecoxib (celebrex) and the anabolic steroid stanozolol. COA of Formula: C3H3N3O2.
Sun, Mingli;Zhou, Yuhui;Li, Laiqiang;Wang, Lei;Ma, Yongmin;Li, Pinhua research published 《 Electrochemically promoted C-3 amination of 2H-indazoles》, the research content is summarized as follows. A metal-free and external oxidant-free electrochem. method for the C-3 amination of 2H-indazoles was reported for the synthesis of indazolyl-amines I [R = n-Bu, 1-pyrazolyl, morpholino, etc.; R1 = H, 5-F, 6-Br, etc.; R2 = Ph, 1-naphthyl, 2-pyridyl, etc.]. The protocol employed com. available azoles and aliphatic amines as amination reagents and had a broad substrate scope, providing the corresponding C3-amination products in high yields at room temperature Mechanistic studies indicated that an oxidative addition/elimination sequence was involved under electrochem. conditions.
2075-46-9, 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%.
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., COA of Formula: C3H3N3O2
