Product Description
2,6-Dichloropyridine (CAS 2402-78-0) is a halogenated pyridine derivative with the molecular formula C?H?Cl?N and a molecular weight of 147.99 Da. It appears as a white to pale yellow crystalline solid with a pungent odor, is slightly soluble in water, and soluble in common organic solvents (e.g., methanol, ethanol, benzene). As a key pharmaceutical and organic synthesis intermediate, it is widely used in the preparation of anti-inflammatory, antibacterial, and central nervous system drugs, as well as in agrochemical and dye synthesis.
Properties

Physical Properties
White to pale yellow crystalline solid with a pungent odor; melting point 83–86 °C, boiling point 211 °C, flash point 110 °C; slightly soluble in water (<1 g/L at 20 °C), soluble in methanol (50 mg/mL) and other organic solvents; stable at room temperature, prone to sublimation.
-
Chemical Properties
A typical aromatic heterocyclic compound with two chlorine atoms at the 2,6-positions of the pyridine ring; undergoes nucleophilic substitution, coupling, and reduction reactions; stable under neutral and weakly acidic conditions, decomposes under strong alkaline or high-temperature conditions.
-
Storage & Safety Properties
- Storage: Keep sealed in a cool, dry, ventilated place (2–8 °C), avoid direct sunlight, moisture, and incompatible substances (e.g., strong bases, oxidants).
- Safety: Irritating to eyes, skin, and respiratory system; avoid inhalation, ingestion, or direct contact; wear protective gloves, goggles, and masks during operation; no flammable or explosive hazards, but may release toxic chloride fumes when heated to decomposition.
