methyl 5-carbamoyl-1-methyl-1H-pyrazole-3-carboxylate; CAS No.: 203792-50-1; methyl 5-carbamoyl-1-methyl-1H-pyrazole-3-carboxylate. PROPERTIES: This compound appears as a white crystalline powder with molecular formula C8H10N3O3 and a molecular weight of 208.18 g/mol. It demonstrates a melting point in the range of 132-136 C and shows moderate solubility in common organic solvents like ethyl acetate and tetrahydrofuran. The substance is sensitive to acidic hydrolysis and should be stored in neutral conditions. Recommended storage involves maintaining in tightly sealed containers at temperatures below 20 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 5-carbamoyl-1-methyl-1H-pyrazole-3-carboxylate may release irritating vapors upon heating. The carbamoyl group requires careful handling in strongly basic environments. APPLICATIONS: In the pharmaceutical industry, methyl 5-carbamoyl-1-methyl-1H-pyrazole-3-carboxylate serves as an intermediate for synthesizing analgesic agents, as described in medicinal chemistry literature focusing on pain management therapies. Its carbamoyl substituent enables formation of bioactive amides through amidation reactions. Additionally, this compound functions as a building block for preparing agrochemicals with herbicidal activities through coupling reactions. Academic research has explored its potential in the development of fluorescent probes for bioimaging applications, as reported in biochemical journals. The methyl substituent also facilitates improved solubility in organic media, making it valuable for preparing pyrazole-based liquid crystalline materials in materials science, as evidenced by studies in polymer chemistry publications.
