CAS 478968-51-3: 2,3-Dihydro-3-oxo-1H-pyrazole-4-carboxylic acid

Description: 2,3-Dihydro-3-oxo-1H-pyrazole-4-carboxylic acid, with the CAS number 478968-51-3, is a heterocyclic organic compound characterized by its pyrazole ring structure, which is a five-membered ring containing two nitrogen atoms. This compound features a carboxylic acid functional group, contributing to its acidic properties. The presence of a keto group (oxo) enhances its reactivity, making it a potential candidate for various chemical transformations. Typically, compounds of this nature exhibit moderate solubility in polar solvents due to the presence of both the carboxylic acid and the keto group, which can engage in hydrogen bonding. The compound may also display biological activity, making it of interest in pharmaceutical research. Its structural features suggest potential applications in medicinal chemistry, particularly in the development of new therapeutic agents. As with many pyrazole derivatives, it may also serve as a building block in the synthesis of more complex molecules. Proper handling and storage are essential, as with all chemical substances, to ensure safety and stability.
