Description

9-BBN Dimer is a highly versatile and reactive organoboron reagent, widely recognized for its role as a hydroborating agent. This compound is essential for facilitating selective and efficient chemical transformations, particularly in the synthesis of complex organic molecules. It is a critical raw material for research and development chemists in the pharmaceutical, agrochemical, and advanced materials sectors seeking to create novel compounds with high precision.

Application

• Hydroboration Reactions: A premier reagent for the stereoselective and regioselective hydroboration of alkenes and alkynes, forming organoboranes for subsequent cross-coupling.
• Pharmaceutical Intermediates: Key building block in the synthesis of active pharmaceutical ingredients (APIs), enabling the construction of specific carbon-boron bonds for Suzuki-Miyaura couplings.
• Agrochemical Synthesis: Used in the production of advanced herbicides, fungicides, and insecticides that require selective functionalization.
• Material Science Research: Employed in the development of organic electronic materials, polymers, and liquid crystals where precise molecular architecture is crucial.
• Asymmetric Synthesis Catalyst Precursor: Serves as a precursor for chiral catalysts used in enantioselective synthesis.
• Organic Synthesis Laboratory: A staple reagent in R&D and process chemistry for the functionalization of complex natural products and novel molecular scaffolds.

Quality Control

Our 9-BBN Dimer is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high reactivity. We provide comprehensive Certificates of Analysis (COA) for each lot, detailing key parameters such as purity, identity, and moisture content. Our quality management system is designed to meet the stringent requirements of research and industrial-scale synthesis.

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. This material is hygroscopic (moisture-sensitive) and easily oxidized; prolonged exposure to air or moisture must be avoided to maintain purity and reactivity.
