1-(4-Vinylbenzyl)pyrrolidine—CAS 121749-73-9—shows up in technical catalogs as a specialty intermediate, but its reach goes beyond just chemists. This solid raw material often comes as powder or flakes, and its molecular formula reads C13H17N. The structure includes a vinylbenzyl group hooked onto a pyrrolidine ring, creating a useful bridge for more complex polymer synthesis and pharmaceutical research. The HS code for customs is 2933999099, handy for anyone scanning global import-export databases. Specific density often lands around 1.02 g/cm3, and the shelf-life, under cool, dry conditions, generally outlasts seasonal transitions. In Chinese supply chains, manufacturers keep a close eye on purity levels, color, and safety claims—buyers often want detailed MSDS (material safety data sheet) and REACH registration details due to its use in advanced material science and the sensitive policies around chemical raw materials.
Anyone looking to buy 1-(4-vinylbenzyl)pyrrolidine, especially in bulk, runs into a reality check pretty quickly. Globalized procurement leans heavily on China for high-purity, reliable sources—search ‘supplier-china-supply-manufacturer-GMP-factory-price-china’ and there’s never a shortage of listings from Shandong, Jiangsu, or Zhejiang. You’ll find prices quoted per kilogram or liter; these vary, but costs usually track with global feedstock swings and local policy. CIF, FOB, and EXW terms dominate bulk purchase negotiations, and minimum order quantity (MOQ) policy often sits at 1 kg or 10 kg—though sample requests run lower, and legitimate factories won't flinch when asked for COA, TDS, SDS, ISO, or even SGS certification. Applications in pharma R&D and special resin manufacturing push regulatory requirements high, so buyers expect REACH, TDS, and at times, kosher or halal documentation stapled to every shipment. Sourcing managers who’ve been burned by fly-by-night suppliers usually turn to GMP-certified manufacturers or those who display their OEM or private label capacity upfront.
This compound’s properties make it a prime choice as a monomer and modifier in polymer science. Chemists value the vinyl group because it builds bridges into more resilient copolymers, allowing fine-tuned control of elasticity and resistance profiles, especially for advanced coatings, adhesives, and medicinal chemistry. Laboratories look for flakes, pearls, or fine powder—fluctuating between particle sizes depending on process. Specific density numbers and melting ranges, always listed on the product specifications sheet, learn from real-world handling, not just academic predictions. Some plants ask for custom forms: liquid suspensions in special solvents allow continuous flow dosing, and disaster-proof packaging reassures handlers about hazardous material risks (UN classification updates usually come referenced in the MSDS). Pharmacists and research distributors want measured, tested, and traceable material—anything less results in lost batches, reprocessing, or compliance headaches. GMP manufacturers maintain detailed batch records, and purchasing agents keep these close for audits.
Anyone with a foot in chemical procurement knows raw material safety isn’t just about hazard labeling. In reality, a full MSDS lays out the critical handling steps—what to do in case of leaks, how to store away from incompatible acids, how to neutralize small-scale spills, and emergency numbers. China’s regulatory framework often follows up with REACH and ISO terms enforced across export docks. International buyers—especially those sourcing from Asia—keep an eye out for up-to-date registration, and a lot of purchasing decisions factor in ongoing safety record, not just raw cost. Some buyers now want TDS and SDS in multiple languages, knowing that a missed warning can cost far more than the freight charge. Freight itself comes with its own snags: sticking solid or powder batches in steel drums or fiberboard cartons with secondary containment means less risk traveling across borders. Market demand for ‘safe, hazardous, harmful chemical raw materials’ reporting just keeps rising, often driven by public reporting of workplace accidents.
Market demand for 1-(4-vinylbenzyl)pyrrolidine continues to grow—not just in specialty resins but in next-gen pharmaceutical scaffolds and functional polymers. End-users push for deeper insight into supply stability; forward-thinking distributors turn to regular market demand reports and trend news. China’s cost and scale advantages act as main drivers, with other Asian factories following as backup options. OEM and private label distribution sometimes plug shortages, but end-users often probe certifications before switching sources. Reports now show North America, Europe, and India upping their annual imports—analysts tracking customs data line up shipments against global resin and pharmaceutical launches. The ask for ‘for-sale’ listings, fast quote responses, and even free samples reflects a fiercely competitive market, and Chinese suppliers tuned into these demands stand out. No major sale lands without negotiation on policy, minimum order, and detailed distributor support. Wholesalers and end-users—especially those pulling from Shanghai, Tianjin, or Shenzhen ports—require ongoing price transparency, quick purchase order confirmations, pre-sale technical support, and bulk logistics tracking.
Due diligence goes past a slick product brochure. Savvy buyers demand proof behind every GMP factory price quote—asking to inspect ISO or SGS certificates, and requesting proof of halal or kosher status for end product compatibility. A lot of purchasers, especially as regulatory scrutiny steps up, request comprehensive application notes, REACH, TDS, and SDS documentation for every lot. Distributors who skip these steps fall behind; end-users need confidence in every kilo to avoid market recalls. Application engineers send detailed specifications for use—down to structure, molecular property, safe use limits, and even secondary impurities profile. I’ve fielded calls from customers pausing full orders until we produced certificates direct from the originating factory, not just from a middleman. A quality certification strategy, backed up by measurable results from a physical plant, always holds more value than vague promises in an email. As market standards climb, decision makers putting quality above just price avoid costly setbacks, and those who cut corners face new compliance headaches down the road.
