Description

9-Allyl-9-Borabicyclo[3.3.1]Nonane is a highly reactive organoboron compound, specifically a 9-BBN derivative, valued for its exceptional selectivity and efficiency in hydroboration reactions. This reagent is a cornerstone in synthetic organic chemistry, enabling the precise synthesis of complex molecules by facilitating the addition of boron-hydrogen bonds across carbon-carbon double bonds. It is an essential tool for researchers and process chemists in the pharmaceutical, agrochemical, and advanced materials sectors who require reliable, high-purity intermediates for constructing novel compounds.

Application

• Selective Hydroboration Agent: Primarily used for the highly regioselective and stereoselective hydroboration of alkenes and alkynes, a critical step in multi-step organic synthesis.
• Pharmaceutical Intermediate Synthesis: Enables the production of key chiral intermediates and active pharmaceutical ingredients (APIs) through controlled functional group transformations.
• Agrochemical Research & Development: Used in the synthesis of novel herbicides, fungicides, and insecticides that require specific stereochemistry.
• Polymer & Material Science: Facilitates the creation of specialty polymers, liquid crystals, and organic electronic materials with tailored properties.
• Asymmetric Synthesis: Serves as a crucial reagent in catalytic and stoichiometric asymmetric reactions to produce enantiomerically enriched compounds.
• Cross-Coupling Precursor: The resulting organoborane products are versatile precursors for Suzuki-Miyaura and other metal-catalyzed cross-coupling reactions.

Quality Control

Our 9-Allyl-9-Borabicyclo[3.3.1]Nonane is manufactured under stringent quality management systems. Each batch undergoes rigorous analytical testing, including NMR (¹H, ¹¹B, ¹³C) and GC/HPLC analysis, to ensure high purity and consistency. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment to support your research and quality assurance protocols.

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 place. Recommended storage temperature is 2-8°C. Due to its moisture-sensitive and easily oxidized nature, containers should be purged with inert gas before resealing after each use.
