Description

9-Borabicyclo[3.3.1]Nonane,9-Phenyl- is a highly versatile and reactive organoboron reagent, specifically a 9-substituted 9-borabicyclo[3.3.1]nonane (9-BBN) derivative. Its core value proposition lies in its exceptional regioselectivity and stability for hydroboration reactions, making it a critical tool for the controlled synthesis of complex organic molecules. This compound is essential for R&D chemists and process engineers in the pharmaceutical, agrochemical, and advanced materials sectors who require precise and efficient synthetic pathways.

Application

• Asymmetric Synthesis: Key chiral intermediate in the production of active pharmaceutical ingredients (APIs) and fine chemicals.
• Selective Hydroboration: Preferred reagent for the anti-Markovnikov addition to alkenes, especially for internal and sterically hindered alkenes, to produce organoboranes for further functionalization.
• Polymer Chemistry: Used in the synthesis and modification of polymers, including the creation of novel polymeric materials with specific properties.
• Cross-Coupling Reactions: Serves as an organoboron precursor in Suzuki-Miyaura cross-coupling reactions to form carbon-carbon bonds.
• Agrochemical Intermediates: Employed in the synthesis of complex molecules for crop protection agents and herbicides.
• Material Science Research: Utilized in the development of organic electronic materials, liquid crystals, and other advanced functional materials.
• Catalyst and Ligand Preparation: Acts as a building block for creating novel catalysts and ligands used in homogeneous catalysis.

Quality Control

Every batch of 9-Phenyl-9-BBN undergoes rigorous analytical testing to ensure high purity, consistency, and performance. Our quality assurance protocols are designed to meet the stringent requirements of research and industrial-scale synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee supply reliability and product traceability.

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, and well-ventilated place. Due to its moisture-sensitive and easily oxidized nature, the container must be kept sealed and allowed to reach room temperature before opening to prevent condensation and degradation.
