Description

3-Chloro-5-Methoxypyridazine Hydrochloride is a high-purity, heterocyclic building block of significant interest in advanced organic synthesis. Its value lies in its dual functionalization, offering reactive handles for further derivatization to create complex molecular architectures. This compound is primarily needed by research chemists and process development scientists in the pharmaceutical and agrochemical industries for the development of new active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) disorders and infectious diseases.
• Agrochemical Research: Used in the development of new herbicides, fungicides, and insecticides, leveraging the pyridazine core's bioactivity.
• Ligand & Catalyst Development: Serves as a starting material for creating specialized ligands used in catalytic processes and metal-organic frameworks (MOFs).
• Material Science: Employed in the synthesis of organic electronic materials and photoactive compounds due to its electron-deficient aromatic system.
• Custom Synthesis & Contract Manufacturing: A critical building block for custom synthesis houses and CDMOs (Contract Development and Manufacturing Organizations) serving global clients.
• Academic & Institutional Research: Used in universities and research institutes for methodological studies in heterocyclic and medicinal chemistry.

Quality Control

Our 3-Chloro-5-Methoxypyridazine Hydrochloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all critical quality attributes. Our commitment is to supply material that meets the exacting standards required for research and development applications.

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 (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
