The pharmaceutical industry is in constant pursuit of novel and effective therapeutic agents, a quest that heavily relies on the availability of high-quality chemical intermediates. Among these, 1-Fluoro-4-iodobenzene (CAS 352-34-1) has established itself as a cornerstone compound, enabling the synthesis of a diverse range of critical pharmaceutical ingredients. For researchers and procurement specialists, understanding its significance and knowing where to efficiently buy this intermediate is crucial for advancing drug development projects.

1-Fluoro-4-iodobenzene, also referred to as p-fluoroiodobenzene, is a valuable aryl halide whose structural features make it highly amenable to various synthetic transformations. The presence of both a fluorine atom and an iodine atom on the benzene ring allows for regioselective reactions, particularly palladium-catalyzed cross-coupling reactions like Suzuki, Sonogashira, and Buchwald-Hartwig amination. These reactions are fundamental in constructing complex molecular scaffolds that form the basis of many modern drugs. For companies actively involved in drug discovery, sourcing this building block from a reputable manufacturer is a strategic necessity.

A primary application for 1-Fluoro-4-iodobenzene in the pharmaceutical sector is its use in the synthesis of kinase inhibitors. Kinase inhibitors are a major class of drugs used to treat various cancers and inflammatory diseases by targeting specific signaling pathways within cells. The precise structure and reactivity of this intermediate allow chemists to efficiently introduce the necessary fluorinated phenyl motifs into these complex drug molecules, thereby modulating their efficacy and pharmacokinetic profiles. When you need to purchase this specific intermediate, focusing on suppliers who guarantee high purity (typically ≥99%) is essential for achieving reliable results.

Beyond kinase inhibitors, 1-Fluoro-4-iodobenzene serves as a versatile precursor for a broader spectrum of pharmaceutical APIs. Its ability to undergo C-C, C-N, and C-O bond formation makes it a key component in assembling diverse heterocyclic systems and other complex organic structures frequently found in pharmacologically active compounds. Access to a stable supply chain for such critical intermediates is vital for pharmaceutical manufacturing. This is where identifying a reliable supplier in China, known for its quality control and production capacity, becomes a significant advantage, often accompanied by competitive pricing.

For effective procurement, understanding the specifications such as CAS number (352-34-1), molecular formula (C6H4FI), and purity is non-negotiable. Companies looking to partner with a manufacturer should also inquire about their production scale capabilities, quality assurance documentation (e.g., Certificates of Analysis), and export experience. A strong supplier relationship can ensure timely delivery and consistent product quality, minimizing disruptions to R&D or production schedules. Securing a favorable price through direct negotiation with manufacturers is also a common practice.

In conclusion, 1-Fluoro-4-iodobenzene (CAS 352-34-1) is an indispensable intermediate for the pharmaceutical industry, facilitating the creation of life-saving medications. Its versatility in synthetic chemistry, particularly in the development of kinase inhibitors, highlights its importance. For seamless project execution, it is imperative to identify and partner with dependable manufacturers and suppliers who can consistently deliver this high-purity compound. When the time comes to buy this critical building block, thorough research into supplier capabilities will ensure success.
