Ethanone, 1-(1-methyl-1H-pyrazol-3-yl)-, also known by its CAS number 137890-04-1, is an organic compound characterized by its pyrazole ring structure, which contributes to its unique chemical properties. This substance features a ketone functional group, specifically an ethanone moiety, linked to a 1-methyl-1H-pyrazol-3-yl substituent. The presence of the pyrazole ring often imparts biological activity, making such compounds of interest in medicinal chemistry. Typically, ethanone derivatives exhibit moderate to high polarity due to the electronegative oxygen atom in the carbonyl group, influencing their solubility in various solvents. The compound may also participate in hydrogen bonding due to the nitrogen atoms in the pyrazole ring. Its reactivity can be attributed to the electrophilic nature of the carbonyl carbon, allowing for various chemical transformations. Overall, this compound's structural features suggest potential applications in pharmaceuticals and agrochemicals, although specific biological activities would require further investigation.
