4-Bromo-2-hydroxybenzonitrile, chemical formula C7H4BrNO, shows up in plenty of industrial labs across China and the globe. This compound falls under the category of halogenated nitriles, designed for serious work in organic synthesis. CAS Number 3252-97-3, HS Code 2926909090, and a density of about 1.7g/cm³ point toward its unique structure and its use as a specialty building block.
The appeal here isn’t just in the structure. Its bromo and hydroxy substitutions on the benzene ring make it a favorite in developing agrochemical intermediates, liquid crystal materials, and pharmaceutical synthesis. Factories and R&D centers want something pure, stable, and well-documented—the specs and the MSDS cover this with clarity. Color ranges from pale tan to nearly white crystals. Keep it dry, cool, and airtight; that’s basic good practice for any reactive raw material. Proper handling and reviewing the SDS matter—this material counts as hazardous and harmful if mishandled.
Buying from a China-based supplier offers both price advantage and robust logistical support. CIF and FOB ports like Shanghai or Ningbo run constant trade in this grade of intermediate, thanks to the high-quality facilities and certification. Factories stay on top of REACH, ISO9001, SGS, and often stretch to demand halal or kosher certification, covering a range of regional needs, especially for overseas clients in the EU, Middle East, or Southeast Asia. Minimum order quantities (MOQ) frequently start at one kilogram, with liter-solution options ready for scale-up. Samples, often free, provide reassurance before signing into a larger purchase.
Labs trust the certificates, TDS, and batch MSDS—these aren’t just bits of paper, but the backbone of compliance and safety. If somebody plans to export or import, a correct HS code smooths customs clearance and regulatory filings. Quality isn’t just about what’s in the drum; it’s as much about what’s on the paperwork.
My years watching chemical supply chains taught me to look for flexibility and transparency. A supplier willing to answer specific questions about the purity (usually >98%), packaging options, and even alternate grades for OEM deals wins trust. Overseas clients check for English documentation and multi-tier certifications. Price matters, but it tends to come second to supply security and documentation—one shipment stopped at customs because of missing REACH data can throw off a whole season’s production plan.
Real issues do pop up: transport regulations keep tightening; safe packaging for hazardous goods takes more effort. Factories need the right barrels, lines for custom labels, and robust packaging to get past international shipping regulations. Sometimes, policies change fast—tariffs, duties, even sudden bans—so a backup plan with multiple suppliers helps keep production running. Good communication, regular updates, and responsive sales channels (WeChat, WhatsApp, even old-fashioned email) make a real difference. It’s not just a matter of raw materials; it's a lesson in supply chain resilience.
Safe use starts with the right training and up-to-date SDS access. Routine audit trails and records on all shipments cut headaches. Dedicated inquiry portals, transparent quoting, and regular price updates help both buyers and sellers. More suppliers post news on batches, certifications, and even new policies—this builds confidence. As more buyers ask for REACH, ISO, SGS, halal, and kosher, suppliers need to keep their docs current, keep sample stock on hand, and offer smaller MOQ for new markets.
The industry keeps adjusting—bringing in digital catalogs, improving inquiry forms, and even OEM options. Clients benefit from detailed product specs, support during customs clearance, and direct feedback channels. Each good batch shipped, each new inquiry answered, builds reputation. As regulations get stricter, clear communication and up-to-date compliance shape the winners in raw materials trade.
