Trimethylsilanecarbonitrile—sometimes called TMSCN—sits in a unique spot among silicon-containing organic chemicals. With the formula C4H9NSi and HS code 2931900090, its structure includes a trimethylsilyl group bonded to a cyanide, making it useful in specialty synthesis. The liquid appears colorless, shows strong volatility, and features a specific density of about 0.76 g/cm3. Chemists value TMSCN for introducing nitrile groups to molecules, unlocking routes in pharmaceutical, agrochemical, and advanced material sectors.
Factories in China stand at the frontline of competitive pricing and reliable supply. Producers present TMSCN with full documentation—MSDS, SDS, sample COAs, and often TDS sheets. This provides necessary transparency. Most large-scale China manufacturers comply with ISO, REACH, and SGS requirements, especially when serving international buyers who need product and packaging to meet safety and environmental standards. Customers can depend on consistent batches, fast delivery, and scalable minimum order quantities (MOQ). Suppliers offer tailored pricing models: FOB or CIF, and some provide OEM or even halal and kosher certified material, ensuring regulatory fit for Europe, Southeast Asia, and the Middle East markets.
Handling TMSCN calls for focus on safe-use policies. Classified as hazardous by global standards, this liquid releases dangerous vapors if heated, and contact or inhalation presents health risks. Reliable suppliers never skip clear hazard labeling and send along extensive safety documentation. Buyers should always review a supplier’s compliance with GHS, inspect the latest MSDS, and train their teams on storage and handling. I remember a site inspection where the absence of proper ventilation in a storage area nearly led to a costly shutdown. All it took was following written SDS guidance and investing in suitable exhaust fans to fix the risk. No raw material should shortcut worker safety—especially in bulk liter solutions or open transfer operations.
Pricing for TMSCN has shifted over recent years as upstream costs—both energy and silicon feedstock—fluctuated. Direct purchasing from China-based producers keeps prices low, cutting out layers of brokers who tend to inflate prices across borders. For anyone new to this chemical, asking for a free sample doesn’t hurt. In fact, many suppliers will ship out a 100 ml trial batch at no charge—testing before making a bulk order protects both parties from setbacks. The biggest factories offer flexible MOQ, sometimes as low as 1 kg, letting startups and university labs get in without heavy risk. Repeat buyers often secure better quotes after a few successful transactions, especially under long-term contracts.
Chemical markets grow strict with international certification. Apart from ISO and SGS, buyers from the European Union look for REACH-registered suppliers before approving purchase orders. Some buyers require halal or kosher certification for added confidence in cross-border applications, particularly when TMSCN serves as a raw material in pharmaceutical intermediates or agricultural product synthesis. Complete documentation should include up-to-date COA, MSDS, and where available, the factory’s facility audit reports.
Trimethylsilanecarbonitrile stays in strong demand as custom manufacturing and advanced synthesis continue to expand. Anyone sourcing or using TMSCN must lean on trusted suppliers with full documentation, and always approach workplace handling with caution. China’s chemical sector now holds a major share of this market, balancing price, quality, and scale for buyers worldwide. Asking the right questions and insisting on proper certifications brings confidence to each transaction—something that matters to both factories and end-users alike.
