4-Bromophthalonitrile has found a steady place in the chemical industry. This compound, with a molecular formula of C8H3BrN2 and CAS No. 1655-43-2, often becomes indispensable for advanced material synthesis, especially for those working in dyes, pigments, and specialty polymers. Its molecular structure, featuring a bromine atom on the phthalonitrile backbone, delivers distinct reactivity and makes it valuable in many research and industrial settings. The HS Code matches 29269090, ensuring proper classification and smooth import-export movement.
This chemical appears as a light beige to pale yellow crystalline solid. The specific density usually hovers around 1.6 g/cm³, giving it stability during storage and transport. Purity often exceeds 98%, confirmed through HPLC or GC analysis. Any supplier worth contacting should readily provide MSDS, REACH, SDS, TDS, and ISO documentation to guarantee traceability and compliance. Understanding the hazards remains crucial: 4-Bromophthalonitrile qualifies as a harmful raw material. Safe handling, proper protective gear, and secure storage help cut down risks during each stage, from receipt at the factory gate to actual chemical synthesis.
Many buyers choose to source 4-Bromophthalonitrile directly from China, where reliable manufacturers and suppliers offer competitive factory prices thanks to scalable production. Most warehouses in Asia follow strict SGS and OEM standards, while some plants even support Halal or Kosher certification requests. Making an inquiry to a reputable China supply chain can unlock bulk pricing models and ensure smoother transit, whether you prefer CIF or FOB shipment terms. Factories usually offer sales quotes in real time, and the minimum order quantity (MOQ) ranges between 1 kg and 25 kg, making sourcing flexible for labs and large plants alike.
Application areas continue to expand. In my experience, many research labs use 4-Bromophthalonitrile for synthesizing phthalocyanines or as an essential building block for high-performance polymers. OEM manufacturers often request free samples to test consistency before agreeing to full production runs. In the world of dyes and pigment production, this raw material remains prized for its chemical reliability and purity.
Those involved in procurement focus not just on raw price but also safe materials, full documentation, and supply chain transparency. I’ve learned that asking for up-to-date MSDS, certification proofs (REACH, SGS, TDS, ISO), and prompt customer support helps build trust. Reputable chemical suppliers should provide details about their hazardous material handling, and sometimes an onsite audit helps verify safety protocols. With China’s evolving chemical safety policy, buyers benefit from staying informed about changes in export standards and international documentation requirements.
For anyone looking to purchase 4-Bromophthalonitrile, the process often starts by requesting detailed specifications and sample COA. Reach out to supplier marketing teams by outlining your anticipated amount, expected packaging form (powder or solution), and any certification needs such as Halal or Kosher. A detailed inquiry showing your interest in MSDS, SDS, CIF, and FOB pricing signals to the supplier that you know what you’re asking for. Many experienced suppliers can also offer quotes within one business day and accommodate both standard lab quantities and full-container loads for factory-scale operations.
As supply chains grow ever more global, a practical approach pays off: look for reliable China-based manufacturers with a history of on-time delivery and authentic certification. Focus on partners who welcome your questions about safety, specifications, and market trends. Safety, full documentation, and quick response to inquiries set apart the best chemical suppliers in this crowded marketplace.
