2-Thenoylacetonitrile (3-Oxo-3-(thiophen-2-yl)propanenitrile) is a versatile heterocyclic building block used in pharmaceutical synthesis and organic transformations. This compound features a melting point of 134-138°C and boiling point of 338.3±22.0°C at 760 mmHg, with a density of 1.256 g/cm³. Its reactive β-ketonitrile structure enables diverse condensation and cyclization reactions, particularly in thiophene-based drug development. The material should be stored sealed in dry conditions at 2-8°C. Safety precautions include wearing protective gloves/eyewear due to potential irritation (GHS Category 2).
