5-Nitro-1H-pyrazole-3-carboxylic acid（Cat No.:R040338）is a nitrogen-rich heterocyclic compound featuring a nitro group at position 5 and a carboxylic acid at position 3 on the pyrazole ring. This molecule is valuable in medicinal and materials chemistry due to its electron-deficient aromatic core and reactive functional groups. The nitro group enhances electrophilicity and facilitates further derivatization, while the carboxylic acid allows for amide bond formation or esterification. Its unique substitution pattern supports applications in designing enzyme inhibitors, agrochemicals, and energetic materials, as well as intermediates in heterocycle synthesis and structure-activity relationship (SAR) investigations.
