Description

4-Pyridinecarbonyl Chloride, 2-Methoxy- (9Ci) is a versatile and reactive chemical building block, specifically an acyl chloride derivative of a methoxypyridine. This compound matters for its role as a key intermediate in the synthesis of more complex molecules, enabling the introduction of the 2-methoxypyridine-4-carbonyl moiety. It is primarily needed by research chemists and process development scientists in the pharmaceutical and agrochemical industries for creating novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: A crucial building block for the synthesis of active pharmaceutical ingredients (APIs), particularly in medicinal chemistry research for developing new drug candidates.
• Agrochemical Synthesis: Used in the research and production of advanced pesticides, herbicides, and fungicides where the pyridine scaffold is a common bioactive component.
• Ligand and Catalyst Preparation: Serves as a precursor for creating specialized ligands used in homogeneous catalysis and coordination chemistry.
• Material Science Research: Employed in the development of organic electronic materials, polymers, and advanced functional materials that incorporate heterocyclic units.
• Custom Synthesis and Contract Manufacturing: A valuable reagent for custom synthesis houses and CDMOs (Contract Development and Manufacturing Organizations) serving the global life sciences sector.

Quality Control

Our 4-Pyridinecarbonyl Chloride, 2-Methoxy- (9Ci) is produced under strict quality management protocols. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing specifications such as assay (by HPLC), identity (by IR/NMR), and impurity profiles are provided and available upon request, supporting your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
