Description

4-(4'-Isopentyloxyphenyl)Phenylboronic Acid is a specialized organoboronic acid derivative, a key building block in modern synthetic chemistry. Its value lies in its role as a versatile coupling partner in Suzuki-Miyaura cross-coupling reactions, enabling the efficient construction of complex biaryl structures. This high-purity intermediate is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors, particularly in the development of novel active ingredients and functional organic compounds.

Application

• Pharmaceutical Intermediate: A crucial precursor in the synthesis of active pharmaceutical ingredients (APIs) and drug candidates, especially those containing complex biphenyl or terphenyl scaffolds.
• Agrochemical Synthesis: Used in the research and production of advanced herbicides, fungicides, and insecticides that require specific biaryl motifs for activity.
• Material Science & OLED Development: Serves as a key monomer or building block for creating organic light-emitting diode (OLED) materials, liquid crystals, and other functional polymers.
• Cross-Coupling Reactions: Primarily employed in palladium-catalyzed Suzuki-Miyaura cross-coupling to form carbon-carbon bonds between aryl groups with high selectivity and yield.
• Chemical Research & Development: A valuable reagent for academic and industrial R&D labs exploring new synthetic methodologies and novel organic compounds.
• Ligand & Catalyst Preparation: Can be utilized to synthesize sophisticated ligands for catalysis or as part of metal-organic frameworks (MOFs).

Quality Control

Our 4-(4'-Isopentyloxyphenyl)Phenylboronic Acid is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including HPLC for purity, NMR for structural confirmation, and Karl Fischer titration for moisture content, to ensure it meets the high standards required for sensitive cross-coupling applications. Certificates of Analysis (COA) with full traceability are provided for every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at a controlled room temperature (15-25°C) in a cool, dry, and well-ventilated area. Due to its sensitivity to oxidation, the container should be sealed immediately after use to minimize exposure to air.
