4,5-Dichlorophthalonitrile draws interest for its crucial role as a raw material in fields like pigments, pharmaceuticals, dyes, and advanced material synthesis. Chemically, this compound comes with a molecular formula of C8H2Cl2N2. Its structure contains two chlorine atoms at the 4 and 5 positions on a benzene ring, plus two cyano (nitrile) groups. The HS Code for 4,5-Dichlorophthalonitrile often lands in the range relevant for organic nitrile intermediates, and its CAS number remains the quickest way to identify it on both supplier and customs documentation. Specific density hovers in the mid-range for cyclic aromatic nitriles, supporting predictable handling in solution and material blend.
The bulk of global demand for 4,5-Dichlorophthalonitrile gets filled by China-based chemical suppliers. Factory-direct price options range from kilogram-level orders up to ton-level bulk, with flexible offerings like free samples for testing. Most manufacturers provide both CIF and FOB terms, giving buyers from Europe, Asia, and the Americas a real chance to compare landed cost before purchase.
Experience says, asking for MSDS, REACH certificates, and SGS/ISO documentation from a China supplier usually comes with no delay. For buyers aiming at export-led finished goods, halal and kosher certified lots widen market reach into more sensitive segments. Production often gets tailored through OEM service, letting clients control purity or packaging right from the sourcing stage.
4,5-Dichlorophthalonitrile brings some handling hazards. It counts as moderately harmful and deserves respect as a hazardous material under GHS labeling. Long sleeves, splash goggles, and good ventilation tackle most operational risks. Standard MSDS sheets highlight its medium toxicity by inhalation and skin contact, so most factories lock it down with dedicated storage and handling protocols. Once dissolved as a liter solution in expert hands, the compound turns into a powerful tool for synthesis. In untrained settings, though, things can go wrong and create legal or environmental headaches.
Policy shifts in regions like the EU or North America sometimes tweak import, storage, or transport rules. One recent piece of advice: request a fresh SDS and TDS document before negotiating MoQ and shipment. Customs agencies in tight regulatory environments often demand this paperwork, alongside proof of proper certification such as REACH or ISO.
Reaching out to a chemical supplier or manufacturer in China means sending a clear inquiry with target specifications, desired MoQ, and end use. Many buyers start with quote requests and adjust order size once technical or safety demands get clarified. Long experience in chemical procurement suggests tracking production batch certificates as well as third-party inspection records—this smooths the import process in places with high compliance standards.
Factory-direct supply also reduces extra cost, with CIF and FOB price comparisons showing how far currency swings affect deals. Most suppliers support OEM labeling and private branding for clients who want control from raw material down to branded ingredient. The process typically only finishes after both sides agree on delivery schedule, safe packaging standards, and rules for returns or claim.
