Thiophene-3,4-dicarbonitrile appears as a pale-yellow crystal and falls into a niche class of heterocyclic compounds, widely recognized by chemists for its utility in both research and industrial sectors. With the molecular formula C6H2N2S and CAS number 2455-27-6, its structure offers a unique blend of sulfur and nitrile groups, inviting interest for specialty synthesis. Common HS-Code placement for this chemical typically comes under 2934, which covers heterocyclic compounds.
The compound's specific density averages around 1.35 g/cm3. Low moisture sensitivity and moderate melting point make storage less troublesome, though all safe material handling procedures should still be followed, especially due to its toxic and hazardous profile outlined in MSDS and SDS documentation.
Experience with thiophene-based materials points to their value in specialty polymers, pharmaceuticals, agrochemical intermediates, and even OLED research. Lab-scale experiments and pilot runs have benefited from the compound's relatively stable shelf life and straightforward handling in both powder and liter solution formats. The nitrile groups offer synthetic flexibility, while the thiophene core brings electron-rich properties, opening doors for advanced organic materials.
Material safety remains a prime concern. The chemical must not contact food, skin, or mucous membranes, echoing the raw material's harmful and hazardous classification on safety data sheets. Strong ventilation, eye protection, gloves, and adherence to TDS guidance matter throughout any handling procedure. Export customers often demand REACH pre-registration, TDS, and compliance certificates—ISO, SGS, Halal, or Kosher—before shipment.
China-supply dominates this space, with dozens of certified manufacturers and suppliers. Trade directories list over 15 verified OEM factories offering rapid inquiry responses, free sample options, and detailed quotes tailored for both batch (MOQ-based) and ton-scale purchases. International buyers commonly negotiate on FOB or CIF terms. While freight surcharges have fluctuated after recent policy shifts, major suppliers keep a stable hand on price and documentation.
Chinese factories tend to stand out for their technical service depth, fast MSDS delivery, and clear labeling for hazardous materials. They work closely with EU and US partners for REACH, SDS, and TDS documentation—vital for those needing additional certifications at the customs window or end-use traceability. Third-party tests, including SGS analysis and ISO-verified batch control, have become standard.
Recent years brought more focus on green chemistry and corporate responsibility, and buyers seek traceability and safe logistics as much as raw performance. News from the latest chemical policy summit in Shanghai showcased pilot programs with improved labeling and QR-coded lot traceability—years ahead of global norms. China suppliers responded fast, adding REACH and GHS-compliant packaging alongside halal and kosher certifications, opening doors for more segments and international partnerships.
For companies looking to switch suppliers or scale up production with thiophene-3,4-dicarbonitrile, proper inquiry matters. Start with a technical and commercial quote. Ask for sample verification and TDS review. Request the latest lot's COA and available ISO or SGS certifications. These precautions take some burden off your compliance team and reduce surprises at the port or during internal audits. Buying directly from a factory or through a trusted marketing agent in China can unlock access to better prices and consistent supply streams.
