Methyl 5-bromo-1-methyl-6-oxo-1,6-dihydropyridazine-3-carboxylate features a brominated dihydropyridazine core with orthogonal functional handles: a methyl group at N1 and a carbonyl at C6. This electron-deficient heterocycle integrates readily into transition-metal-catalyzed couplings and serves as a scaffold for diversification in medicinal chemistry and agrochemical synthesis.
Methyl 5-bromo-1-methyl-6-oxo-1,6-dihydropyridazine-3-carboxylate serves as a versatile building block for heterocyclic synthesis, enabling efficient access to substituted pyridazines via palladium-catalyzed cross-coupling and nucleophilic displacement reactions. Its bromine and ester functionalities offer orthogonal reactivity, facilitating downstream derivatization in medicinal chemistry and process development. The molecule exhibits good bench stability and is readily purified by standard chromatographic methods.
