Description

2-Chloro-6-Methyl-Pyridine-3-Sulfonyl Chloride is a high-purity, multi-functional chemical intermediate essential for advanced organic synthesis. This compound matters because its dual reactive sites—the sulfonyl chloride and chloro-substituted pyridine ring—make it a versatile building block for constructing complex molecular architectures. Pharmaceutical, agrochemical, and specialty chemical R&D teams need it for the development of novel active ingredients, particularly sulfonamides and heterocyclic compounds.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), especially those containing sulfonamide or pyridine moieties.
• Agrochemical Synthesis: Used in the research and production of advanced herbicides, fungicides, and insecticides.
• Ligand and Catalyst Development: Serves as a precursor for creating specialized ligands in transition metal catalysis and organocatalysis.
• Material Science Research: Employed in the development of functional polymers, dyes, and advanced organic materials.
• Custom Synthesis and Contract Manufacturing: A critical starting material for fine chemical manufacturers offering bespoke synthesis services.

Quality Control

Our 2-Chloro-6-Methyl-Pyridine-3-Sulfonyl Chloride is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and GC-MS, to ensure high chemical purity and consistency. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

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