Description

9-Ethyl-9-Borabicyclo[3.3.1]Nonane is a highly reactive organoboron compound, widely recognized as 9-BBN-H. It serves as a versatile and selective hydroborating agent, offering superior regioselectivity for terminal alkenes compared to other boranes. This makes it an indispensable intermediate in organic synthesis, particularly for the production of fine chemicals and active pharmaceutical ingredients (APIs). It is primarily utilized by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials sectors.

Application

• Selective Hydroboration: Key reagent for the regioselective hydroboration of terminal alkenes, a critical step in synthesizing primary alcohols.
• Pharmaceutical Intermediates: Used in the synthesis of complex drug molecules and active pharmaceutical ingredients (APIs) where precise functional group transformation is required.
• Agrochemical Synthesis: Employed in creating advanced pesticide and herbicide intermediates.
• Polymer & Material Science: Acts as a building block or modifying agent in the development of specialty polymers and functional materials.
• Asymmetric Synthesis: Used in conjunction with chiral ligands or auxiliaries to create enantiomerically enriched compounds.
• Cross-Coupling Reactions: Serves as a boron source in Suzuki-Miyaura cross-coupling reactions after transmetalation.
• Academic & Industrial R&D: A staple reagent in research laboratories for developing novel synthetic methodologies.

Quality Control

Our 9-Ethyl-9-Borabicyclo[3.3.1]Nonane is manufactured under strict quality protocols to ensure batch-to-batch consistency and high reactivity. We provide comprehensive Certificates of Analysis (COA) for each lot, detailing purity and assay results. Our quality management system is designed to meet the stringent requirements of cGMP and ISO standards for advanced chemical intermediates.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) in a cool, dry, and well-ventilated area. Due to its highly volatile and hygroscopic nature, the container must be kept tightly sealed and handled in a moisture-free environment. Recommended storage temperature is 2-8°C for long-term stability.
