Description

Boronic Acid, B-[4-(Cyclopentyloxy)-2,3-Difluorophenyl]- is a high-value, organoboron building block characterized by its unique difluorophenyl and cyclopentyloxy substituents. This compound matters as a critical intermediate in modern synthetic chemistry, enabling the formation of carbon-carbon bonds via Suzuki-Miyaura cross-coupling reactions. It is primarily needed by research institutions and pharmaceutical companies engaged in the development of novel active pharmaceutical ingredients (APIs), agrochemicals, and advanced materials.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of complex drug candidates, particularly in oncology and central nervous system (CNS) therapeutic areas.
• Agrochemical Research: Used to construct novel pesticide and herbicide molecules with enhanced efficacy and selectivity.
• Material Science: Building block for creating functionalized polymers, liquid crystals, and organic electronic materials.
• Suzuki-Miyaura Cross-Coupling: Essential reagent for palladium-catalyzed coupling reactions to form biaryl structures, a fundamental transformation in medicinal chemistry.
• Chemical Biology Probes: Utilized in the development of sensors and probes for studying biological processes.
• Process Chemistry & Scale-up: Serves as a reliable intermediate for the kilogram-scale production of target molecules under GMP-like conditions.

Quality Control

Our Boronic Acid, B-[4-(Cyclopentyloxy)-2,3-Difluorophenyl]- is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and elemental analysis, to ensure high purity and batch-to-batch consistency suitable for research and scale-up applications. Certificates of Analysis (COA) with full specifications are available upon request.

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 nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent moisture absorption and decomposition.
