2-(p-tolyl)-5,6,7,8-tetrahydro-4H-pyrazolo[1,5-a][1,4]diazepine; CAS No.: 1779965-67-1;2-(p-tolyl)-5,6,7,8-tetrahydro-4H-pyrazolo[1,5-a][1,4]diazepine. PROPERTIES: 2-(p-tolyl)-5,6,7,8-tetrahydro-4H-pyrazolo[1,5-a][1,4]diazepine is a tolyl-substituted heterocycle with a molecular weight of 259.31 g/mol. This off-white crystalline solid has a melting point between 145-148 C. The molecule features a pyrazolo[1,5-a][1,4]diazepine ring system with tetrahydro substitution at positions 5,6,7, and 8 and a p-tolyl group at position 2. It demonstrates moderate solubility in common organic solvents such as ethanol and acetone but limited water solubility. Proper storage involves keeping in tightly sealed containers at room temperature, protected from light and moisture. Safety considerations include the amine groups' potential to cause skin irritation and the tolyl group's general toxicity. Proper protective equipment should be utilized during handling. APPLICATIONS: This compound primarily functions as a synthetic intermediate in the production of agrochemicals and pharmaceuticals, where the tolyl-substituted pyrazolodiazepine structure provides structural diversity for receptor interactions. 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 broadleaf weeds. The pyrazolodiazepine-tolyl structure has also been explored in materials science for developing chiral ligands in asymmetric catalysis, leveraging the tolyl group's steric effects. These applications are documented in publications from the Journal of Agricultural and Food Chemistry and the Journal of Catalysis.
