2,3-Dichlorothiophene is an important halogenated heterocyclic compound used as a key intermediate in pharmaceutical and agrochemical synthesis. This flammable liquid (Flash Point: 59°C) has a boiling point of 173-174°C at 760 mmHg and density of 1.456 g/mL at 25°C. It exhibits characteristic thiophene reactivity while the chlorine substituents enable diverse functionalization. The compound should be stored under inert atmosphere at 2-8°C due to moisture sensitivity. Safety precautions are critical as it is toxic if swallowed (GHS Category 3) and causes severe eye damage (GHS Category 1). Its unique structure makes it valuable for constructing bioactive molecules and functional materials.
