Description

6-Chloro-4-methylpyridazin-3-amine features a chlorinated pyridazine core with a methyl group at C4 and an amino substituent at C3, delivering enhanced electron density for coupling reactions. This bench-stable heterocycle integrates readily into kinase inhibitors and pharmaceutical scaffolds, offering high reactivity under standard conditions.

Application

6-Chloro-4-methylpyridazin-3-amine serves as a versatile building block in medicinal chemistry, enabling efficient access to pyridazinone-based scaffolds through nucleophilic substitution and coupling reactions. Its chlorine at C6 facilitates regioselective functionalization, while the methyl group enhances metabolic stability. The compound exhibits good bench stability and compatibility with standard synthetic workflows, supporting rapid diversification for drug discovery applications.
