Description

Monochloroborane-Dioxane Complex 3.0M is a versatile organoboron reagent, specifically a stabilized complex of monochloroborane with 1,4-dioxane, supplied as a 3.0 molar solution. This compound is a valuable source of the BH2Cl synthon, offering enhanced stability and handling characteristics compared to the free borane species. It is primarily utilized in advanced organic synthesis, serving as a key intermediate for pharmaceutical research, agrochemical development, and the production of specialty polymers and materials.

Application

• Hydroboration Reactions: A key reagent for the selective hydroboration of alkenes and alkynes, providing access to functionalized alkyl- and alkenylboronates.
• Pharmaceutical Intermediates: Used in the synthesis of complex drug molecules, particularly in the construction of carbon-boron bonds for Suzuki-Miyaura cross-coupling reactions.
• Polymer & Material Science: Acts as a monomer or modifying agent in the production of boron-containing polymers, resins, and advanced ceramic precursors.
• Agrochemical Synthesis: Employed in the creation of novel active ingredients for crop protection products.
• Asymmetric Synthesis: Useful in the preparation of chiral boron reagents for stereoselective transformations.
• Reductive Amination & Other Functional Group Reductions: Serves as a selective reducing agent in organic synthesis.

Quality Control

Our Monochloroborane-Dioxane Complex 3.0M is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed to confirm concentration, identity, and the absence of critical impurities. A comprehensive Certificate of Analysis (COA) detailing assay, solvent content, and impurity profiles is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and reacts with strong acids/organic solvents; keep the container tightly sealed under an inert atmosphere (argon/nitrogen) and away from incompatible materials.
