2,5-Dichlorothiophene is a halogenated heterocyclic compound widely used as a key intermediate in pharmaceutical and agrochemical synthesis. This liquid exhibits a boiling point of 162°C (lit.) and density of 1.442 g/mL at 25°C, with a refractive index of 1.561-1.563. It is insoluble in water but soluble in organic solvents. The compound should be stored in sealed containers at 2-8°C under inert atmosphere. Safety precautions include wearing protective gloves/eyewear due to its irritating properties (GHS Category 2). Its unique structure makes it valuable for constructing thiophene-based bioactive molecules and functional materials.
