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. Product Details of C3H3N3O2.
Morikawa, Masa-aki;Yang, Hanyu;Ishiba, Keita;Masutani, Kouta;Hui, Joseph K.-H.;Kimizuka, Nobuo research published 《 A Liquid Arylazopyrazole Derivative as Molecular Solar Thermal Fuel with Long-term Thermal Stability》, the research content is summarized as follows. A liquid arylazopyrazole derivative is newly synthesized as mol. solar thermal fuel. It shows efficient trans-to-cis photoisomerization in the neat liquid state, with the cis-isomer having a significantly longer thermal half-life (t1/2 = 3,069 h, at 25°C). It overcomes the limited thermal stability of the corresponding liquid cis-azobenzene derivative (t1/2 = 16 h) and marked a gravimetric energy d. of 41 kJ·mol-1, which meets the requirement for thermophys. heat storage applications.
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., Product Details of C3H3N3O2
