3-Chlorothiophene is a halogenated heterocyclic compound widely used as a key intermediate in pharmaceutical and agrochemical synthesis. This reactive building block features a boiling point of 133.9±13.0°C at 760 mmHg and density of 1.276 g/mL at 25°C (lit.). With its refractive index of 1.553 (n20/D), it serves as a versatile precursor for conducting polymers and bioactive molecules. The compound should be stored in dark, sealed containers at 2-8°C under inert atmosphere. Safety precautions include wearing protective gloves/eyewear due to flammability (Flash point 37°C) and potential skin/eye irritation (GHS Category 2).
