3-bromo-1H-pyrazolo[4,3-d]pyrimidine-5,7(4H,6H)-dione; CAS No.: 2703752-87-6; 3-bromo-1H-pyrazolo[4,3-d]pyrimidine-5,7(4H,6H)-dione. PROPERTIES: This compound presents as a white to off-white crystalline solid with molecular formula C7H3BrN4O2 and a molecular weight of 261.02 g/mol. It exhibits a melting point in the range of 240-244 C and demonstrates moderate solubility in polar solvents such as dimethylformamide and dimethyl sulfoxide. The substance is hygroscopic and should be stored in dry conditions. Recommended storage involves maintaining in tightly sealed containers at room temperature with protection from moisture and light. When handling, standard laboratory safety precautions should be observed, including the use of gloves and eye protection, as 3-bromo-1H-pyrazolo[4,3-d]pyrimidine-5,7(4H,6H)-dione may release irritating vapors upon heating. The bromo group requires careful handling in strongly basic environments. APPLICATIONS: In the pharmaceutical industry, 3-bromo-1H-pyrazolo[4,3-d]pyrimidine-5,7(4H,6H)-dione serves as an intermediate for synthesizing non-steroidal anti-inflammatory drugs (NSAIDs), as described in medicinal chemistry literature focusing on pyrazole derivatives. Its bromo substituent enables participation in cross-coupling reactions for constructing biaryl systems. Additionally, this compound functions as a building block for preparing agrochemicals with fungicidal activities through nucleophilic aromatic substitution reactions. Academic research has explored its potential in metal coordination chemistry for creating luminescent sensors, as reported in inorganic chemistry journals. The pyrazolopyrimidine ring system also facilitates formation of metal-organic frameworks (MOFs), making it valuable for gas storage applications in materials science, as evidenced by studies in crystallography publications.
