1-Bromopyrrolidine-2,5-dione means more than just another name in a catalog of chemical compounds. On paper, it has a molecular formula of C4H4BrNO2, and chemists often see it as N-Bromosuccinimide—shorthand NBS. This simple-looking raw material plays a major role in laboratories and manufacturing facilities alike. Structurally, it tracks as a solid compound, appearing as flakes, powder, or sometimes crystalline pearls, all typically showing a white to off-white color. With a specific density hovering near 2.1 g/cm³, the compound fits right into workflows relying on solution mixing, as the liter-to-mass calculation stays reliable. Most factories, especially in China, emphasize their GMP, REACH, ISO, and sometimes Halal/Kosher certifications in supplying high-quality 1-Bromopyrrolidine-2,5-dione, recognizing market push for traceable, safe chemicals.
Handling this compound means staying sharp about safety: its MSDS (Material Safety Data Sheet) calls for gloves, goggles, and good ventilation. NBS is labeled as hazardous—not on the same level as certain industrial acids or solvents, but it can still irritate skin and eyes, so attention to engineering controls and safe handling makes a difference. That explains why bulk suppliers from China, with established factory-direct routes, emphasize up-to-date SDS, TDS, and Quality/TDS documentation. I remember ordering samples from a top-rated manufacturer in Shandong; after sorting out the minimum order quantity (MOQ) and CIF/FOB quotes, what arrived matched its HS Code (2933.3900), confirming traceability—a big deal for compliance under the latest global market demand and supply chain policies.
The unique property of N-Bromosuccinimide lies in its ability to selectively brominate allylic and benzylic positions under mild conditions. This means it keeps popping up in pharmaceuticals, agrochemicals, solvent formulations, and new materials research. Factories run steady demand from drug discovery groups chasing new intermediates. In polymer chemistry, it helps modify macromolecular backbones. Some buyers look at bulk volume for resin synthesis, others deal with gram or kilogram lots to support ongoing academic research. China-based suppliers offer plenty of flexibility: from OEM packaging to OEM branding options, direct factory prices, or distributor terms tailored for large-scale production or R&D lab use. The market signals show increasing demand linked to strict regulatory policies driving toward certified and low-impurity raw materials. Quality certification through ISO, SGS, Halal, Kosher, and TDS reflects a push for global acceptance.
Material structure and consistent specs matter for process repeatability. In my own projects, keeping a close line to a supplier who could confirm molecular property, density, and purity for each batch helped keep unwanted by-products at bay. Every time a market report lists flammable, hazardous, or harmful chemicals, regulators raise the bar for raw material suppliers. Factories shift to automated, closed-loop packaging, so the workers stay clear of any fine dust or powder exposure. China’s top exporters win business in Europe and Southeast Asia with these process guarantees, plus the lure of attractive factory pricing and the ability to accommodate a wide range of sample or bulk orders—everything from free trial grams to wholesale container loads.
Global buyers scout reliable suppliers offering consistent stock, fast inquiry response lines, and solid bulk packaging. Application-side users, from pharma companies to electronic materials firms, demand samples first—inquiry and quote, test run, safety checked clearing regulatory lines for hazardous chemicals. Each client values clear labeling: HS code, exact molecular structure, batch purity, MSDS/SDS transparency. Policy updates, often slow to reach factories out west, tend to land quickly at large Chinese manufacturing zones, which now employ supply chain auditing, REACH compliance, and OEM capability as standard. Distributors juggling free sample requests, export restrictions, and custom documentation for bulk CIF orders look to suppliers who lead on policy communication and spot market shifts before they disrupt production.
Product certifications—the backbone for easing overseas customs friction—are now the rule, not the exception. Small-lot buyers value ISO and GMP tags as assurance of traceable, batch-tracked powders and flakes; bigger buyers in the EU look for REACH, SGS, or Halal-Kosher certificates to clear internal audits. Some routes open for solution sales (liquid phase) or direct powder transfers for immediate functionalization. Bulk buyers, large or small, count on suppliers who post live market demand reports and can quote new prices fast. Factory price matters in this competitive landscape, paired with a clear sample and MOQ process, updated TDS/MSDS, and proof of safe storage and transport.
Market stability draws strength from suppliers with a clear track record: presence in China’s chemical hubs, visible online order support, open inquiry paths for quote/sample requests, plus commitment to quality certification. As competition grows, manufacturers with control from raw material sourcing to refinement and OEM-blended packaging carve out better deals for both the sample buyer and bulk distributor. Real-world users—from pharma chemists to electronics techs—rely on consistency between lot numbers, batch-specific molecular checks, and a transparent process for purchase, quote, sample, and regulatory document delivery. Factories step up with automatic density checks, pre-shipping COA certificates, and clear labeling that matches every local and international compliance guide. Certification by REACH, TDS, OEM, and kosher/halal bodies locks in new partnerships across Asia, Europe, and North America, bending the market toward certified, traceable, and reliable supply.
