Description

2,3-Dichloroisonicotinoyl 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 development 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 novel heterocyclic compounds.

Application

• Pharmaceutical Intermediate: A critical precursor in the synthesis of novel drug candidates, particularly those containing the isonicotinamide or nicotinamide pharmacophore.
• Agrochemical Synthesis: Used in the development of next-generation herbicides, fungicides, and insecticides with enhanced efficacy.
• Material Science Research: Serves as a monomer or cross-linking agent in the creation of specialized polymers and functional materials.
• Chemical Biology Probes: Employed in the design and synthesis of molecular probes for studying enzyme function and biological pathways.
• Custom Synthesis & Contract Manufacturing: A vital starting material for custom synthesis houses and CDMOs (Contract Development and Manufacturing Organizations) serving the life sciences industry.

Quality Control

Our 2,3-Dichloroisonicotinoyl Chloride is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure identity, purity, and consistency. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all critical quality attributes. Our commitment is to supply material that meets the exacting standards required for research and cGMP manufacturing.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening. Recommended storage temperature is 2-8°C for long-term stability.
