Benzonitrile, 4-Iodo-, a popular aromatic nitrile bearing CAS number 624-72-6, has become a critical building block across fine chemical and pharmaceutical industries. Featuring a benzene ring connected to a nitrile group and an iodine atom in the para position, it draws interest for its reactivity and versatility in synthesis. Chemists value the distinct molecular formula C7H4IN and its notable molecular weight of 229.02 g/mol. Bright white to off-white crystalline powder describes its common appearance. Specific density settles around 1.8 g/cm3. Material typically melts around 49-53°C, making it easy to handle in labs and scale-up environments.
Benzonitrile, 4-Iodo- holds HS Code 2926909090 for export, which simplifies customs processing. Industry spec sheets detail purity above 98%, low water content, and absence of related impurities. Both REACH registration and ISO/SGS documentation are available for global supply chain compliance. Material safety data sheets (MSDS/SDS) and technical datasheets (TDS) support responsible handling, covering flammability, toxicity, and safe storage instructions thanks to its classification as a hazardous but manageable raw material.
Over my years sourcing specialty chemicals, China-based suppliers have proven fast, price-competitive, and consistent for intermediates like Benzonitrile, 4-Iodo-. Hundreds of manufacturers now offer flexible minimum order quantity (MOQ)—many as low as 1 kg, sometimes down to a few hundred grams for R&D. Factory quotes regularly beat hyper-inflated distributor prices elsewhere. Suppliers based in cities such as Shanghai, Hangzhou, and Tianjin bring the benefit of shortened supply chains and direct OEM/ODM opportunities. Export-ready, certified, and halal/kosher options suit requirements from buyers worldwide.
Chinese plants often ship both small and bulk orders by air and sea, giving a choice of CIF or FOB delivery terms to ports across Europe, North America, the Middle East, and Southeast Asia. Certifications often show REACH registration, ISO 9001 and 14001, SGS-testing, and the ability to provide COA, TDS, and MSDS for documentation. Halal and kosher certifications open paths for regulated end uses, which matters for pharma and agrochemical customers following strict procurement policies.
Benzonitrile, 4-Iodo- features in constructing active pharmaceutical ingredients, agrochemicals, dyes, and liquid crystal materials. Whether used as a raw starting material or for downstream transformation, the presence of para-iodine modifies reactivity and enables coupling chemistry. Availability as a high-purity solid or as a custom solution in liter volumes adapts to various lab and pilot plant workflows. The chemical’s hazardous label—due to potential toxicity and environmental impact—demands correct handling: ventilated workspaces, PPE, and strict adherence to waste protocols.
Anyone considering Benzonitrile, 4-Iodo-, as a research or production material, needs a recent MSDS for up-to-date hazard and first aid advice. Companies must keep staff trained on storage, transport labeling, and emergency procedures. News updates in the industry point toward supply policy shifts, such as stricter customs controls or REACH modifications in the EU. Responsible chemical handling, product stewardship, and up-to-date certifications now drive buyer decisions.
Sourcing direct from a China-based supplier means sending an inquiry for technical data, regulatory documents, and a quote including CIF, FOB, or DDP pricing. Many vendors offer free samples for evaluation. International buyers should confirm MOQ, delivery timeline, and product freshness. Whether for small research batches or multi-ton manufacturing needs, verifying OEM standards and third-party certification supports a lasting supplier relationship.
