Factories in China continue to shape the global market for specialty chemicals. 1H-Indole-4-Carbonitrile draws steady attention not only from pharma labs but also from pigment, agrochemical, and advanced material manufacturers. With China’s competitive factory price structures, cost-effective supply and scalable manufacturing options become available to international buyers. Large chemical supply hubs, such as Shanghai and Jiangsu, maintain plenty of inventory and prompt CIF or FOB shipment to the EU, US, and Southeast Asia.
Bulk buyers who need quick MSDS (Material Safety Data Sheet) uploads and up-to-date TDS (Technical Data Sheet) documents often request them along with quotes. It helps compliance teams verify hazard statements, safe handling procedures, storage, and SDS compatibility with local regulations such as REACH or ISO. I remember, from my own lab sourcing work, that a missing density or melting point data point can hold up an import process for days. Reliable Chinese suppliers tend to get this right on the first go, with full paperwork including SGS or third-party test results, halal, kosher, and even OEM certifications if requested.
1H-Indole-4-Carbonitrile holds the molecular formula C9H6N2 with a HS Code—most often classified under 2933990099 by Customs for export. As a light yellow to off-white crystalline solid, it typically posts a specific density of 1.23 g/cm3, and dissolves well in common organic solvents. In practice, factories supply 1-10 liter solution material, often for use as raw material in synthesis or compounding, though kilo-scale powder bulk is widely available for research scale.
Buyers must note that as a hazardous chemical, it calls for solid PPE use in handling. Though not classified as acutely toxic, it can cause irritation and needs containment and exhaust protocols during use and transfer. A trustworthy supplier always rushes clear hazardous labeling, drum safety closure, and includes MSDS in both English and Chinese.
Most Chinese manufacturers invite direct inquiry through their sales team. Minimum order quantities (MOQ) vary. For R&D, a factory may accept as little as 500 grams, but for stable price per kilo, full drum purchase secures the lowest rate. Recent deals range from USD 150 to USD 250 per kilo depending on purity, batch size, and season. Bulk CIF/FOB quotes pack better value, especially for established clients who request quarterly shipments.
Once, during a negotiation for our life sciences group, a good supplier offered a free sample—just a 100 gram pack—to demonstrate batch consistency. For long-term buyers, such test samples make a difference. It becomes easy to gauge whether the batch conforms to ISO or SGS certification and meets stricter Western market policy. Full REACH or TDS documentation means regulatory inspections move faster.
With global rules tightening, responsible buyers check for halal and kosher certification if finished goods enter sensitive markets. If a material flows into a regulated supply chain, all paperwork—from MSDS to packing certificates—matters. TDS, SDS, and batch certificates are no longer optional. This builds trust and protects the manufacturer, brand, and end-user alike.
Clear communication with suppliers, requesting full product specs and clear batch history, stands out as the best way to navigate the chemical-buy landscape today. From my own background in chemical sourcing, it always pays to spend an extra hour vetting before sending the PO. A complete, well-documented chemical shipment reduces risk and smooths the journey from raw material to finished, compliant goods.
