Description

9-Borabicyclo[3.3.1]Nonane, 9-[(1-Methylethyl)Thio]- is a specialized organoboron compound, specifically a hindered thioether-substituted 9-BBN derivative, valued for its unique reactivity as a hydroboration reagent and synthetic intermediate. Its primary commercial value lies in enabling highly selective hydroboration reactions, particularly for the synthesis of complex organic molecules where regioselectivity and functional group tolerance are critical. This compound is essential for R&D and production chemists in the pharmaceutical, agrochemical, and advanced materials sectors who require precise boron-based transformations.

Application

• Selective Hydroboration Agent: Used for the controlled hydroboration of alkenes and alkynes, offering complementary selectivity to other boron reagents like catecholborane.
• Pharmaceutical Intermediate Synthesis: A key building block in the synthesis of active pharmaceutical ingredients (APIs), especially for creating chiral centers and complex carbon skeletons.
• Agrochemical Product Development: Employed in the research and production of novel pesticides and herbicides requiring specific boron-containing motifs.
• Polymer & Material Science: Serves as a functionalization agent or initiator in the development of specialty polymers and advanced organic materials.
• Asymmetric Synthesis: Utilized in conjunction with chiral ligands or auxiliaries to perform enantioselective transformations in fine chemical manufacturing.
• Cross-Coupling Reactions: Acts as a boron source in Suzuki-Miyaura and other transition metal-catalyzed cross-coupling reactions to form carbon-carbon bonds.

Quality Control

Every batch of our 9-Borabicyclo[3.3.1]Nonane, 9-[(1-Methylethyl)Thio]- undergoes rigorous analytical testing to ensure high purity and consistent performance. We adhere to strict in-house quality standards suitable for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to guarantee traceability and meet your quality assurance requirements.

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 sensitivity to oxidation and moisture, the container should be kept sealed and allowed to reach ambient temperature before opening to minimize condensation.
