Ethyl 3-methyl-1H-pyrazole-5-carboxylate Usage And Synthesis

Chemical Properties	White to yellow solid
Uses	Ethyl 3-Methyl-5-pyrazolecarboxylate is a useful synthetic intermediate. It is used to prepare tetrahydroisoquinoline amide substituted Ph pyrazoles as selective Bcl-2 inhibitors. It is also studies as a hypolipidemic agent.
Uses	Ethyl 3-methylpyrazole-5-carboxylate may be used to synthesize the following ligands: potassium salt of new dihydrobis(3-carboxyethyl-5-methylpyrazolyl)borate (Bp^COOEt,Me) [(3-carboxy-5-methyl-1H-1-pyrazolyl) (3-methyl-5-carboxy-1H-1-pyrazolyl)methane, which readily forms Zn(II) and Cd(II) complexes bis(3-carboxy-5-methyl-1H-1-pyrazolyl)methane, which readily forms Zn(II) and Cd(II) complexes
General Description	Ethyl 3-methylpyrazole-5-carboxylate can be prepared by reacting ethyl acetylpyruvate and hydrazine.
