2,3-Dichloropyridine is a halogenated pyridine derivative widely used as a key intermediate in pharmaceutical and agrochemical synthesis. This compound exhibits a melting point of 65-69°C and boiling point of 192.5°C at 760 mmHg. With a density of 1.388 g/cm³ and vapor pressure of 0.679 mmHg at 25°C, it serves as a crucial building block for insecticides (e.g., chlorantraniliprole) and antibacterial agents. The material should be stored in sealed containers under inert atmosphere at 2-8°C. Safety precautions include wearing protective gloves/eyewear due to its irritant properties (GHS Category 2). Its molecular structure enables selective functionalization at the 2- and 5-positions for further derivatization.
