Description

3,5-Dichloropyridine-2-carbonyl chloride is a high-purity, reactive chemical intermediate essential for advanced organic synthesis. This compound matters for its role as a key building block in the creation of complex molecules, particularly in the pharmaceutical and agrochemical sectors. It is primarily needed by R&D chemists and process development scientists working on active pharmaceutical ingredients (APIs), crop protection agents, and specialty fine chemicals.

Application

• Pharmaceutical Intermediate: A crucial precursor in the synthesis of novel drug candidates, particularly those containing a pyridine core, such as kinase inhibitors and other biologically active molecules.
• Agrochemical Synthesis: Used in the manufacturing of advanced herbicides, fungicides, and insecticides where the dichloropyridine moiety imparts specific biological activity.
• Ligand and Catalyst Development: Serves as a starting material for creating specialized ligands used in metal-catalyzed cross-coupling reactions and other catalytic processes.
• Material Science Research: Employed in the development of organic electronic materials, dyes, and photoactive compounds.
• Custom Synthesis and Contract Manufacturing: A vital reagent for custom synthesis houses and CDMOs (Contract Development and Manufacturing Organizations) serving the life sciences industry.

Quality Control

Our 3,5-Dichloropyridine-2-carbonyl chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, GC, and NMR, to ensure high purity and consistency. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition. Keep away from heat, open flames, and incompatible materials such as strong bases, alcohols, and water.
