Description

3-Bromo-6-Ethylpyridazine is a versatile brominated heterocyclic building block of significant importance in modern organic synthesis. Its core value lies in its reactive bromine substituent, which enables efficient cross-coupling reactions and functional group transformations, making it a critical intermediate for constructing 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 advanced materials.

Application

• Pharmaceutical Intermediate: A key synthon in the research and development of novel drug candidates, particularly in medicinal chemistry programs targeting CNS disorders and oncology.
• Agrochemical Synthesis: Used in the creation of advanced herbicides, fungicides, and insecticides, leveraging the pyridazine core for bioactivity.
• Ligand and Catalyst Development: Serves as a precursor for synthesizing specialized ligands used in homogeneous catalysis and material science.
• Organic Electronic Materials: Employed in the synthesis of conjugated molecules and polymers for applications in OLEDs and organic semiconductors.
• Chemical Research & Development: A fundamental building block for method development in cross-coupling (e.g., Suzuki, Negishi) and nucleophilic substitution reactions.
• Custom Synthesis and Contract Manufacturing: Supplied to CDMOs for the production of bespoke compounds and scaled-up processes under cGMP guidelines where required.

Quality Control

Our 3-Bromo-6-Ethylpyridazine is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC, GC, NMR, and mass spectrometry for identity confirmation and impurity profiling. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting the exact specifications and results. We support development and production needs across various standards, including research grade and cGMP for advanced pharmaceutical 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). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent degradation. Keep away from heat and incompatible materials.
