methyl 1H-pyrazolo[3,4-c]pyridine-7-carboxylate; CAS No.: 1140240-00-1; methyl 1H-pyrazolo[3,4-c]pyridine-7-carboxylate. PROPERTIES: This compound appears as a white to off-white crystalline solid with molecular formula C9H7N3O2 and a molecular weight of 193.17 g/mol. It exhibits a melting point in the range of 148-152 C and demonstrates moderate solubility in common organic solvents like methanol and ethyl acetate. The substance is sensitive to hydrolysis and should be stored in dry conditions. Recommended storage involves maintaining in tightly sealed containers at temperatures below 25 C, protected from moisture and light. When handling, standard laboratory safety protocols should be followed, including the use of protective gloves and eye wear, as methyl 1H-pyrazolo[3,4-c]pyridine-7-carboxylate may cause skin irritation. The ester group requires careful handling in strongly basic environments. APPLICATIONS: In the pharmaceutical industry, methyl 1H-pyrazolo[3,4-c]pyridine-7-carboxylate serves as an intermediate for synthesizing non-steroidal anti-inflammatory drugs (NSAIDs), as described in medicinal chemistry literature focusing on pyrazole derivatives. Its ester substituent enables improved solubility in organic media for formulation purposes. Additionally, this compound functions as a building block for preparing agrochemicals with fungicidal activities through hydrolysis reactions. Academic research has explored its utility in the development of fluorescent probes for bioimaging applications, as reported in biochemical journals. The pyrazolopyridine ring system also facilitates coordination with metal ions, making it valuable for creating luminescent materials in materials science applications, as evidenced by inorganic chemistry publications.
