Product Description
2,3-Dichloropyridine, widely recognized across the chemical synthesis industry under industry-standard aliases such as 2,3-DCP and Pyridine, 2,3-dichloro-, stands as a foundational intermediate for advanced agricultural and pharmaceutical formulations. Presenting as a finely milled white crystalline solid with a molecular weight of 147.99 g/mol, it carries a faint, characteristic pyridine odor. The compound demonstrates excellent solubility in common organic solvents while remaining only micro-soluble in water, a specific chemical profile that makes it highly reactive and perfectly suited for complex heterocyclic compound synthesis. Manufactured to meet rigorous agrochemical and pharmaceutical grade requirements, it serves as the primary building block for chlorantraniliprole, active pharmaceutical ingredients (APIs), and other advanced amide-based pest control solutions. By utilizing a highly controlled proprietary synthesis route, the production minimizes waste emissions and maintains exceptional batch-to-batch consistency. Procurement teams and formulation scientists rely on this core intermediate to drive formulation stability, optimize overall production yields, and ensure strict compliance with environmental safety frameworks across the global green chemical value chain.

Every batch undergoes rigorous chromatographic analysis to verify that the active content strictly exceeds the 99.0% threshold, consistently achieving a 99.5% purity level. The precise control over isomeric impurities—specifically maintaining 2,5-Dichloropyridine and 2,6-Dichloropyridine well below their maximum limits—ensures that downstream synthesis reactions proceed without unwanted side-chain interferences. Furthermore, keeping the moisture content strictly below 0.3% prevents degradation and caking during transit, preserving the material's free-flowing crystalline structure for immediate integration into large-scale reactor applications.
Mode of Action & Performance Data
Key Role
Acting as a vital electrophilic scaffold, 2,3-Dichloropyridine enables the precise construction of complex amide bonds necessary for next-generation insecticides. Its structural geometry allows formulators to efficiently synthesize active pharmaceutical ingredients (APIs) and advanced agrochemicals, directly improving the efficacy of pest management solutions without compromising crop safety or environmental standards.
Production Process
The manufacturing protocol leverages a continuous pyridine chlorination and targeted reduction pathway. By integrating multi-stage distillation and automated crystallization post-treatment, the process effectively isolates the desired isomer. This continuous loop not only purifies the compound but also stabilizes the output, ensuring that large-scale procurement demands are met with uniform chemical behavior.

Safety & Handling
Safety Symbols and Codes
Classified under GHS07 with the signal word “Warning,” this compound requires careful administrative controls. It carries hazard statements H315, H319, and H335, alongside EU risk codes R22 and R36/37/38. Operators must strictly adhere to safety phrases S26, S36, and S37/39 during all handling phases to ensure workplace compliance.
Protective Equipment
Personnel must be equipped with NIOSH-approved N95 particulate respirators, chemical-splash goggles, and heavy-duty nitrile gloves. Standard laboratory exhaust hoods or local ventilation systems are mandatory to prevent the accumulation of airborne crystalline dust and maintain safe breathing zones.
Transportation and Storage
While not regulated as a highly hazardous material for standard freight, preserving its 99.5% purity requires strict environmental controls. Store the 25kg bags in a cool, well-ventilated, and dry warehouse, strictly away from strong oxidizing agents and direct sunlight. Maintaining ambient temperatures and low humidity ensures the product remains stable without caking, guaranteeing an extended shelf life for global transit.
