4-Sulfanylbenzonitrile has carved out a role as a key raw material in pharmaceuticals, fine chemicals, and polymer research. Buyers searching for reliable suppliers need transparency—not just in chemical specifications, but in pricing, factory background, and certification. Dealing directly with a manufacturer in China often brings up crucial questions around factory price, supply consistency, and safety documentation. In my years of working with chemical import projects, I have learned that shortcuts on supplier qualifications often cost time, resources, and safety down the line.
Looking at the details, 4-Sulfanylbenzonitrile carries the CAS number 104-90-5 and features a molecular formula of C7H5NS. Its structure brings a benzonitrile ring, swapped at the para position for a sulfanyl group. This isn’t just textbook chemistry—this structure enables nucleophilic substitution for downstream synthesis in dyes, pharmaceuticals, and agrochemical intermediates. Physical data indicate a specific density around 1.24 g/cm3, solid at room temperature, and mostly handled in pure powder or granule form. Buyers checking compliance will ask for MSDS and SDS safety sheets for guidelines on safe storage and handling. The material is listed under HS Code 2930909099.
Much of the world’s volume supply comes from China, where manufacturers follow ISO and SGS certification standards. Serious buyers can request documents proving halal, kosher, REACH, or OEM certification status, especially for clients in regulated markets. My past purchasing trips to mainland factories always centered on verifying clean production records, timely shipping schedules, and a real-time response to inquiries about quality. Suppliers who encourage pre-shipment QC inspections and chase SGS results show an extra layer of accountability that's essential for global supply deals.
Price remains a make-or-break issue—particularly for 4-Sulfanylbenzonitrile, where minor purity differences cause wild swings in offer quotes from factory to sales agent. Direct purchase from the Chinese manufacturer does cut costs, but it's crucial to lock in MOQ (minimum order quantity) terms and choose between FOB or CIF logistics. For sea-freight CIF, full documentation, safe packing, and customs-clear SDS files make all the difference. Some vendors supply free samples for TDS testing and R&D screening—one of the best low-risk ways to check material quality without up-front capital risk.
No experienced buyer ignores safety in procurement talks. 4-Sulfanylbenzonitrile rates as hazardous—avoid skin and eye exposure, use proper gloves and splash-proof goggles, and set up local ventilation. MSDS details acute and chronic risk, while shipping cartons need the right UN labels and handling codes. In my own shipments, correct labeling and clear policy communication to customs brokers avoided a cascade of delays during port entry. Customers working on liter-scale solutions or production-scale batches need clear guidance on compatible materials and safe disposal pathways, all checked against regional chemical policies.
Savvy procurement professionals weigh supplier response times, technical support, and transparency in documentation before placing a purchase order. Sending a clear inquiry, with your specs, required certifications, and planned application, speeds up the quotation process. Reliable sellers will support you through the steps—shipping, customs, and final product handover. With knowledge and careful sourcing, 4-Sulfanylbenzonitrile serves as a dependable, safe, and well-documented raw material for the right buyer.
