Description

3-Amino-5-Chloropyridazine is a versatile heterocyclic building block of significant interest in advanced organic synthesis. Its bifunctional nature, featuring both an amino group and a chlorine atom on the pyridazine ring, makes it a critical intermediate for constructing complex molecular architectures. This compound is primarily utilized by research institutions and industrial R&D departments in the pharmaceutical and agrochemical sectors for the development of novel active ingredients.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of novel drug candidates, particularly for central nervous system (CNS) and anti-infective agents.
• Agrochemical Synthesis: Used in the research and development of new herbicides, fungicides, and insecticides, leveraging its heterocyclic core.
• Ligand and Catalyst Development: Serves as a starting material for creating specialized ligands used in catalytic processes and metal-organic frameworks (MOFs).
• Material Science Research: Employed in the synthesis of organic electronic materials and functional dyes due to its electron-deficient pyridazine structure.
• Custom Synthesis and Contract Manufacturing: A fundamental building block for custom chemical synthesis services targeting specialized, high-value compounds.

Quality Control

Our 3-Amino-5-Chloropyridazine is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation via IR and NMR spectroscopy, to ensure it meets the high standards required for research and development applications. A Certificate of Analysis (COA) detailing all test results is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed to prevent moisture absorption, which may affect product stability and performance.
