Pyrazoles are synthesized by the reaction of α,β-unsaturated aldehydes with hydrazine and subsequent dehydrogenation. 2075-46-9, formula is C3H3N3O2, Name is 4-Nitro-1H-pyrazole. Substituted pyrazoles are prepared by condensation of 1,3-diketones with hydrazine (Knorr-type reactions). For example, acetylacetone and hydrazine gives 3,5-dimethylpyrazole. COA of Formula: C3H3N3O2.

A novel series of copper-activatable drugs intended for use against methicillin-sensitive Staphylococcus aureus (MSSA) and methicillin-resistant S. aureus (MRSA) were synthesized, characterized, and tested against the MSSA strain Newman and the MRSA Lac strain (a USA300 strain), resp. These drugs feature an NNSN structural motif, which enables the binding of copper. In the absence of copper, no activity against MSSA and MRSA at realistic drug concentrations was observed Although none of the novel drug candidates exhibits a stereocenter, sub-micromolar activities against SA Newman and micromolar activities against SA Lac were observed in the presence, but not in the absence, of bioavailable copper. Copper influx is a component of cellular response to bacterial infections, which is often described as nutritional immunity.
COA of Formula: C3H3N3O2, 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., 2075-46-9.
