Description

(8-Carboxyoctyl)Triphenylphosphonium Bromide is a high-purity, functionalized phosphonium salt widely used as a key reagent in organic synthesis and materials science. Its unique structure, featuring a long-chain carboxylic acid terminus, makes it an invaluable precursor for the synthesis of specialized polymers, catalysts, and biologically active compounds. This product is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials industries seeking to incorporate specific functional groups via Wittig-type reactions or as phase-transfer catalysts.

Application

• Pharmaceutical Intermediate: A crucial building block for synthesizing complex drug molecules, particularly those requiring lipophilic cation moieties or specific chain extensions.
• Polymer Chemistry: Used as a monomer or functionalization agent in the production of specialty polymers, including ionomers and polymers with tailored surface properties.
• Catalysis: Serves as a precursor for generating novel phosphine ligands and phase-transfer catalysts used in cross-coupling and other transition metal-catalyzed reactions.
• Agrochemical Synthesis: Employed in the research and development of advanced pesticides and herbicides that require specific cationic or amphiphilic structures.
• Materials Science: Acts as a surface modifier or a component in the fabrication of functional materials, such as liquid crystals and self-assembled monolayers (SAMs).
• Bioconjugation: Utilized in biochemical research for labeling or modifying biomolecules via its reactive carboxyl group.

Quality Control

Our (8-Carboxyoctyl)Triphenylphosphonium Bromide is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR for structural confirmation, and residual solvent analysis, to ensure it meets the high standards required for research and industrial synthesis. A detailed Certificate of Analysis (COA) is provided with every shipment to guarantee traceability, consistency, and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after each use to prevent degradation from atmospheric moisture. For long-term storage, consider using desiccants.
