Description

5-Methoxypyridazine-3-Carboxylic Acid is a high-purity heterocyclic carboxylic acid building block of significant interest in advanced organic synthesis. This compound serves as a critical intermediate for the development of novel active pharmaceutical ingredients (APIs) and agrochemicals, enabling precise molecular modifications. It is primarily utilized by research and development chemists, process development scientists, and manufacturers in the pharmaceutical, agrochemical, and specialty chemical industries seeking to incorporate functionalized pyridazine motifs into their target molecules.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, particularly in kinase inhibitor and central nervous system (CNS) active compound research.
• Agrochemical Synthesis: Used in the development of next-generation herbicides, fungicides, and plant growth regulators that require specific heterocyclic scaffolds.
• Ligand and Catalyst Development: Serves as a precursor for creating specialized ligands used in metal-catalyzed cross-coupling reactions and other catalytic processes.
• Material Science Research: Employed in the synthesis of organic electronic materials, such as charge-transport layers or light-emitting components, due to its electron-deficient pyridazine core.
• Custom Synthesis and Contract Manufacturing: A vital starting material for custom synthesis houses and CDMOs (Contract Development and Manufacturing Organizations) producing bespoke compounds for client projects.

Quality Control

Every batch of 5-Methoxypyridazine-3-Carboxylic Acid is manufactured under strict quality management systems and undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Our standard quality commitment includes HPLC purity ≥97% (typical), with detailed impurity profiling available. Certificates of Analysis (COA) are provided with each shipment, documenting compliance with agreed specifications. We support development projects with custom purity grades and analytical method development 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). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation and maintain product integrity.
