For procurement managers and R&D scientists in the chemical and pharmaceutical industries, identifying reliable sources for critical raw materials is a constant challenge. 1,4-Bis(diphenylphosphino)butane (DPPB), with its CAS number 7688-25-7, is one such essential compound, frequently sought after for its utility as a pharmaceutical intermediate and a highly effective ligand in organic synthesis. This guide aims to assist buyers in understanding DPPB and navigating the process of sourcing it from reputable manufacturers and suppliers.

DPPB is a white crystalline powder characterized by its high purity, typically ≥98%, and a low moisture content, ensuring its suitability for sensitive chemical reactions. Its molecular formula is C28H28P2, and it possesses a molecular weight of approximately 426.47 g/mol. Key physical properties include a melting point in the range of 132-136 °C. These specifications are crucial for applications in pharmaceutical synthesis and catalysis, where consistency and purity directly impact the success of the final product. Buyers often look to purchase DPPB in bulk to meet production demands.

The primary demand for DPPB stems from its role as a pharmaceutical intermediate. It is integral to the multi-step synthesis of various active pharmaceutical ingredients (APIs). For drug development companies, securing a consistent supply of high-quality DPPB is non-negotiable. As a manufacturer based in China, we are well-positioned to offer competitive pricing and ensure a stable supply chain, providing peace of mind for procurement professionals. Inquire about our competitive price for DPPB when you plan your next purchase.

Furthermore, DPPB's significance as a bidentate phosphine ligand in catalysis cannot be overstated. It is a key component in palladium-catalyzed cross-coupling reactions, essential for building complex organic molecules. Researchers and process chemists leverage DPPB's unique properties to drive reactions such as C-C and C-N bond formation with high efficiency and selectivity.
