3,4-Thiophenedicarbonitrile(CAS: 18853-32-2)

3,4-Thiophenedicarbonitrile (CAS: 18853-32-2) is a colorless solid with a molecular weight of approximately 134.12 g/mol. It has a low solubility in water but is soluble in organic solvents like ethanol and acetone. Chemically, it is relatively stable but can react with strong bases to form thiophene derivatives. It crystallizes in a monoclinic form.

3,4-Thiophenedicarbonitrile can be synthesized by the condensation of thiophene-2-carbonitrile with thiophene in the presence of a Lewis acid catalyst like aluminum chloride. The reaction yields a high purity product with good selectivity and high yield, typically around 90%.

3,4-Thiophenedicarbonitrile (CAS: 18853-32-2) is used in various industries including pharmaceuticals, where it serves as a precursor for drug synthesis, and in the production of semiconductors and sensors. Its stability and chemical reactivity make it valuable in these applications.

When handling 3,4-Thiophenedicarbonitrile (CAS: 18853-32-2), it is essential to use appropriate personal protective equipment (PPE) such as gloves and safety goggles. Store it in a fume hood and avoid contact with water to prevent hydrolysis. In case of spill, use appropriate spill cleanup materials and consult the Safety Data Sheet (SDS) for detailed instructions.
