Description

β-Benzyl-9-BBN is a highly versatile and valuable organoboron reagent, specifically a 9-borabicyclo[3.3.1]nonane (9-BBN) derivative. This compound is crucial for its role in facilitating highly selective hydroboration reactions, particularly for internal alkenes, which are fundamental transformations in modern synthetic organic chemistry. It is an essential tool for researchers and process chemists in the pharmaceutical, agrochemical, and advanced materials sectors, enabling the efficient and stereoselective synthesis of complex molecules.

Application

• Selective Hydroboration Agent: Primary reagent for the controlled hydroboration of internal and terminal alkenes, offering superior regioselectivity compared to other boranes.
• Pharmaceutical Intermediate Synthesis: Key building block in the multi-step synthesis of active pharmaceutical ingredients (APIs), where precise functional group installation is required.
• Agrochemical Production: Used in the creation of novel pesticides and herbicides, leveraging its ability to introduce boron-containing motifs for further cross-coupling.
• Polymer & Material Science: Employed in the synthesis of specialty polymers and advanced organic materials with tailored properties.
• Asymmetric Synthesis: Serves as a precursor or reagent in catalytic asymmetric hydroboration processes to create chiral alcohols and derivatives.
• Cross-Coupling Reactions: The resulting organoborane adducts are pivotal substrates in Suzuki-Miyaura cross-coupling reactions for carbon-carbon bond formation.

Quality Control

Our β-Benzyl-9-BBN is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity, essential for reproducible research and process scale-up. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, identity, and impurity profiles. Our quality systems are designed to meet the stringent requirements of R&D and cGMP environments for non-GMP starting materials.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) at 2-8°C in a cool, dry place. Due to its moisture-sensitive and easily oxidized nature, the container should only be opened in a controlled, dry environment and resealed immediately after use.
