This pyridazinone scaffold integrates a sterically hindered oxan-2-yl group and two chlorine substituents at the 4,5-positions, enhancing metabolic stability and enabling selective conjugation in bioconjugation workflows.
4,5-Dichloro-2-(oxan-2-yl)pyridazin-3-one serves as a versatile building block for heterocyclic synthesis, enabling efficient construction of pyridazinone-based scaffolds. The dichloro substitution pattern facilitates nucleophilic aromatic substitution, while the oxan-2-yl group provides a stable, polar handle for further derivatization. Its bench stability and compatibility with standard coupling protocols make it well-suited for medicinal chemistry campaigns and process development.
