clear colorless to light yellow liquid | [Uses]
1-Methylpyrazole is a useful synthetic intermediate. It is used to synthesize heteroaryl(fluorophenyl)piperidinylindoles as α1 adrenoceptor antagonists. It is also used to prepare quinazoline derivatives as glucokinase activators. | [Definition]
ChEBI: A member of the class of pyrazoles that is the 1-methyl derivative of 1H-pyrazole. | [Synthesis]
1-Methylpyrazole was prepared by the condensation of 1,1,3,3-tetraethoxypropane with methylhydrazine[1]. | [References]
