Thiophene-3-Carbonitrile turns up in labs and factories as a solid building block for pharmaceuticals, dyes, and specialty chemicals. Chemists work with this intermediate when aiming for substances that call for both sulfur and nitrile functionalities. The structure, C5H3NS, combines a thiophene ring with a cyano group at the 3-position.
Looking at specifications, its HS Code falls within 29349990, covering various heterocyclic compounds. Typical purity reaches above 98%, with molecular weight at 109.15 g/mol. The density is commonly listed around 1.19 g/cm³. Solid at room temperature, it dissolves fairly in organic solvents like dichloromethane or ethanol — hardly budging in water. The formula shows a highly reactive corner that gets chemists interested for derivative syntheses.
China’s chemical network delivers bulk lots through established supplier and manufacturer channels, often operating directly from the factory level. Exporters open the gate for both CIF and FOB shipping terms, helping product reach across continents. Many buyers ask about minimum order quantity (MOQ) — with most China-based suppliers working with lots ranging from just a kilo to full pallet volumes. For inquiry and fast quote, English language sales teams usually supply specs, COA, and free samples, especially for first-time buyers worrying about quality.
Price varies with purity and batch size. Direct factory connections help buyers access competitive deals, and established suppliers share detailed MSDS, TDS, and reach certification paperwork.
On the material safety front, Thiophene-3-Carbonitrile requires careful storage and handling. Its MSDS flags hazards typical for nitrile- and sulfurous-organics: toxic if inhaled or swallowed, and irritating for skin and eyes. Factories using this compound equip workers with gloves, masks, and goggles. Nobody wants to skip on a robust risk assessment.
Many factories support REACH compliance, answering downstream partner needs in the EU. Certification game steps up: suppliers increasingly offer ISO 9001, SGS third-party testing, TDS, and kosher/halal certification to cover global regulatory and end-market requirements. This provides confidence on traceability and responsible manufacture, easing the concerns many importers raise during audits.
Thiophene-3-Carbonitrile appears in the synthesis of active pharmaceutical ingredients, advanced material science, and as a starting point for crop science innovation. As global demand rises for clean and certified raw materials, chemical trading policies shift to encourage more transparent sourcing from China. Recent trade updates push exporters to meet stricter SDS and hazard-labelling standards, with harmonized documentation making customs clearance less painful for international buyers.
Several buyers press for custom formulation (OEM/ODM) contracts, requesting SDS, TDS, and even kosher/halal certification depending on market. Asian suppliers answer with a broader mix of compliance paperwork, digital MSDS, and technical data. Quality control teams run batch testing for every shipment, uploading COA and third-party SGS results for each container dispatched.
Those using Thiophene-3-Carbonitrile face a landscape where technical guidance, safety compliance, and transparent China-sourced supply carry real weight. Steady relationships with reliable suppliers beat risky spot market buys. In my experience, buyers stretching for detailed specification sheets ('spec') and hands-on MSDS review come out ahead — both in terms of product reliability and keeping audit risks low.
