4-(4,4,5,5-Tetramethyl-1,3,2-dioxaborolan-2-yl)-1H-pyrazole-1-carboxamide (CAS 1926961-39-8) has a molecular formula of C??H??BN?O? and molecular weight of 237.06 g/mol, with a dioxaborolane group at C4 and a carboxamide group at the pyrazole N1-position. As a boron-containing pyrazole derivative, it is a key intermediate in pharmaceutical synthesis (via Suzuki-Miyaura coupling) and agrochemical R&D. It requires sealed, dry storage to protect the boronate moiety from hydrolysis, ensuring reactivity for cross-coupling reactions.
