Description

4,6-Dichloro-3-Methylpyridazine is a halogenated pyridazine derivative serving as a versatile and critical building block in advanced organic synthesis. Its value lies in its reactive dichloro substitution pattern, which allows for selective functionalization to create complex heterocyclic scaffolds. This intermediate is primarily needed by pharmaceutical R&D and agrochemical manufacturers for the development of new active ingredients.

Application

• Pharmaceutical Intermediate: Key synthon for the research and development of novel drug candidates, particularly in central nervous system (CNS) and anti-infective therapeutic areas.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and insecticides, leveraging the pyridazine core for bioactivity.
• Material Science Research: Serves as a precursor for the synthesis of specialized ligands, organic electronic materials, and photoactive compounds.
• Chemical Reference Standard: Employed as an analytical standard in quality control laboratories for method development and validation.
• Custom Synthesis & Contract Manufacturing: A fundamental starting material for custom chemical synthesis services targeting specialized, low-volume fine chemicals.

Quality Control

Our 4,6-Dichloro-3-Methylpyridazine is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including HPLC for purity and identity confirmation by IR and NMR spectroscopy, to ensure it meets the high standards required for synthetic applications. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your regulatory and quality assurance needs.

Storage

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