From my experience in the fine chemicals sector, 3,4-Thiophenedicarbonitrile stands out as a core building block for pharmaceutical and electronic application research. Chemists value it for its straightforward structure: C6H2N2S, packing two nitrile groups on a thiophene ring. With a specific density around 1.36 g/cm3 and a melting point near 170°C, this solid raw material changes the conversation in synthesis planning. Its HS Code—2926909090—aligns with common global customs language, smoothing international movement and tracking.
Having bought chemicals for years, direct lines to Chinese suppliers usually mean sharper factory prices for 3,4-Thiophenedicarbonitrile. Plenty of exporters advertise both small MOQ and bulk, offering flexible shipment by CIF or FOB, often with free samples for qualified customers. Reliable Chinese producers carry REACH, ISO, SGS, Halal, and Kosher certifications, which really matters in regulated markets. Getting an accurate quote means providing your specs, testing requirements, and desired purity—often above 98% for demanding applications.
Every raw material brings responsibility. This one is flagged hazardous in its MSDS: harmful if swallowed, irritates eyes and skin, and not friendly to aquatic environments. Anyone working with this compound should follow the SDS instructions without shortcuts. Gloves, goggles, and good ventilation protect staff, while compliance with local waste rules keeps labs out of trouble. Most manufacturers supply the full TDS and COA by request. Third-party verification, like SGS, provides confidence in risk management.
Spec sheets spell out crystal appearance, tight melting point range, and minimal impurity profiles. Buyers often seek 25kg drum packaging or smaller sealed liters for bench-scale orders. Bulk buyers benefit from stable supply contracts and regular order cycles. OEM packaging offers extra value for distributors keeping brands distinct. Not every producer matches every spec request, but the best can tailor size, documentation, and transit options fast enough to support both R&D and commercial purchase cycles.
Fresh news from China’s export market shows stable supply and price, as feedstock costs remain predictable this year. Price movement links to upstream sulfur chemicals and global logistics policy more than end-user demand shifts. Policy around REACH and GHS remains a focus, with regular updates on compliance and international chemical trade. Buyers purchasing for regulated EU markets check for recent SDS and TDS updates before sale. The ability to request and verify documentation creates a clearer procurement loop. Versatility in dye, electronics, or pharmaceutical intermediate applications keeps this molecule in demand, shifting only with major raw material or policy swings.
3,4-Thiophenedicarbonitrile delivers reliability from certified Chinese suppliers, competitive manufacturer pricing, and detailed technical documentation. Chemical buyers with experience lean into supply stability, complete MSDS and REACH compliance, and straight communication on quote and MOQ for new and repeat orders. International users rarely compromise on certification or traceability, keeping both lab work and large-scale production moving ahead safely and efficiently.
