Application
3-Chloro-6-hydrazinopyridazine (CAS 17284-97-8) is a versatile heterocyclic building block featuring a chlorine atom at the 3-position and a hydrazine group at the 6-position. This pyridazine derivative is widely used in medicinal chemistry and pharmaceutical research as a key intermediate for the synthesis of biologically active molecules, including kinase inhibitors, antimicrobial agents, and anti-inflammatory compounds. The hydrazine moiety enables the construction of pyridazinone, triazole, and pyrazole derivatives via cyclocondensation reactions, while the chlorine atom allows nucleophilic aromatic substitution and cross-coupling reactions (Suzuki-Miyaura, Buchwald-Hartwig) for further diversification. This scaffold facilitates rapid structure-activity relationship (SAR) studies in drug discovery, particularly for developing targeted cancer therapies and central nervous system (CNS) agents. It is also utilized in agrochemical research for herbicide and fungicide development. High purity ensures reproducible results in high-throughput screening and scalable GMP synthesis.
