Description

9-Borabicyclo[3.3.1]Nonane (9-BBN) is a highly versatile and widely used organoboron reagent, particularly valued for its exceptional regioselectivity and stability in hydroboration reactions. Its primary commercial value lies in enabling the efficient synthesis of complex organic molecules, including pharmaceutical intermediates and fine chemicals, with high purity and predictable outcomes. This compound is essential for R&D chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials sectors who require reliable and selective synthetic tools.

Application

• Selective Hydroboration: A premier reagent for the highly selective hydroboration of alkenes and alkynes, particularly terminal olefins, to produce organoboranes for subsequent cross-coupling reactions.
• Pharmaceutical Intermediates: Critical in the synthesis of key chiral and achiral intermediates for active pharmaceutical ingredients (APIs), enabling streamlined routes to complex drug molecules.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and insecticides where selective functionalization is required.
• Polymer & Material Science: Employed in the functionalization of polymers and the creation of novel organic electronic materials and liquid crystals.
• Asymmetric Synthesis: Serves as a precursor to chiral boron reagents for enantioselective transformations in fine chemical manufacturing.
• Organic Synthesis Research: A fundamental tool in academic and industrial laboratories for method development and the construction of complex natural products.

Quality Control

Our 9-Borabicyclo[3.3.1]Nonane is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high performance. We provide comprehensive analytical data, including NMR (¹¹B and ¹H) and GC/HPLC analysis, to verify purity and identity. Certificates of Analysis (COA) detailing all specifications are available upon request, supporting compliance in cGMP and ISO 9001 environments where applicable.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) at 2-8°C in a cool, dry, and well-ventilated place. Due to its hygroscopic and easily oxidized nature, containers must be carefully sealed immediately after use to exclude moisture and air.
