3-Iodopyridine is a halogenated pyridine derivative widely used as a versatile building block in pharmaceutical synthesis and organic transformations. This compound has a melting point of 53-56°C (lit.) and boiling point of 90-92°C at 14 mmHg, with a density of 1.957 g/cm³. It exhibits characteristic reactivity for transition metal-catalyzed cross-coupling reactions (e.g., Suzuki, Negishi couplings). The material is light-sensitive and should be stored sealed under inert atmosphere at 2-8°C. Safety precautions are necessary due to its irritant properties (GHS Category 2), requiring protective gloves/eyewear during handling.
