Description

3,3-Dimethylallylboronic Acid Pinacol Ester, 2-(3-Methyl-But-2-Enyl)-4,4,5,5-Tetramethyl-1,3,2-Dioxaborolane is a high-purity organoboron reagent, specifically a protected boronic ester derivative. This compound is a critical building block in modern synthetic chemistry, enabling the efficient formation of carbon-carbon bonds via cross-coupling reactions. It is primarily utilized by pharmaceutical, agrochemical, and advanced materials research and development teams for the synthesis of complex organic molecules.

Application

• Suzuki-Miyaura Cross-Coupling Reactions: A key reagent for introducing the 3,3-dimethylallyl (prenyl) group into aromatic and heteroaromatic systems to create novel chemical entities.
• Pharmaceutical Intermediate Synthesis: Used in the research and production of active pharmaceutical ingredients (APIs), particularly in the construction of complex natural product analogs and drug candidates.
• Agrochemical Development: Employed in the synthesis of novel herbicides, fungicides, and plant growth regulators that require specific prenylated structures.
• Material Science Research: Serves as a monomer or functionalization agent in the development of organic electronic materials, polymers, and liquid crystals.
• Chemical Biology & Probe Synthesis: Useful for labeling and modifying biomolecules or creating activity-based probes for biological studies.
• Process Chemistry & Scale-up: Provides a stable, storable alternative to more sensitive boronic acids for large-scale manufacturing processes.

Quality Control

Our production of 3,3-Dimethylallylboronic Acid Pinacol Ester adheres to stringent quality management protocols to ensure batch-to-batch consistency and high chemical purity. Each lot undergoes comprehensive analytical characterization, including NMR (1H, 13C, 11B), GC/HPLC, and Karl Fischer titration, to confirm identity, purity, and moisture content. A detailed Certificate of Analysis (COA) is provided with every shipment, and we support compliance with REACH and other global regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic nature, the container should be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation.
