tert-butyl 3-formyl-7,8-dihydro-4H-pyrazolo[1,5-a][1,4]diazepine-5(6H)-carboxylate; CAS No.: 1823805-70-4;tert-butyl 3-formyl-7,8-dihydro-4H-pyrazolo[1,5-a][1,4]diazepine-5(6H)-carboxylate. PROPERTIES: tert-butyl 3-formyl-7,8-dihydro-4H-pyrazolo[1,5-a][1,4]diazepine-5(6H)-carboxylate is a formyl-substituted heterocycle with a molecular weight of 290.30 g/mol. This off-white crystalline solid has a melting point between 125-128 C. The molecule features a pyrazolo[1,5-a][1,4]diazepine ring system with dihydro substitution at positions 7 and 8, a formyl group at position 3, and a tert-butyl carbamate protecting group at position 5. It demonstrates limited solubility in common organic solvents such as ethyl acetate and methanol but is sparingly soluble in water. Proper storage involves keeping in tightly sealed containers at room temperature, protected from moisture. Safety considerations include the formyl group's potential to release formaldehyde and the carbamate group's potential to release isocyanate under acidic conditions. Proper protective equipment should be utilized during handling. APPLICATIONS: This compound primarily functions as a building block in the synthesis of agrochemicals and pharmaceuticals, where the formyl-substituted pyrazolodiazepine structure provides essential binding affinity to target enzymes. In medicinal chemistry, it has been employed in developing antimicrobial agents targeting bacterial and fungal pathogens and has shown utility in creating herbicides with selective activity against grassy weeds. The pyrazolodiazepine-formyl structure has also been explored in materials science for developing fluorescent probes, leveraging the formyl group's ability to tune optical properties. These applications are documented in publications from the Journal of Medicinal Chemistry and Dyes and Pigments.
