Description

1,3,2-Dioxaborolane, 2-(1-Cyclononen-1-Yl)-4,4,5,5-Tetramethyl- is a specialized organoboron reagent featuring a cyclic dioxaborolane (pinacol boronate ester) structure. This compound is valued for its role as a versatile synthetic intermediate in advanced organic synthesis, particularly in cross-coupling reactions. It is primarily utilized by research chemists and process development scientists in the pharmaceutical, agrochemical, and materials science industries to construct complex molecular architectures.

Application

• Suzuki-Miyaura Cross-Coupling Reactions: A key reagent for forming carbon-carbon bonds between the boronate ester and aryl/vinyl halides, essential for constructing biaryl and conjugated systems in drug discovery.
• Pharmaceutical Intermediate Synthesis: Used in the research and development of active pharmaceutical ingredients (APIs), enabling the introduction of the cyclononenyl moiety into target molecules.
• Agrochemical Research: Serves as a building block for creating novel compounds with potential herbicidal, fungicidal, or insecticidal activity.
• Materials Science & Organic Electronics: A precursor for synthesizing organic semiconductors, liquid crystals, or polymers where the specific cyclic structure influences material properties.
• Chemical Biology & Probe Development: Can be employed to create tagged molecules or bioconjugates for studying biological processes.
• Catalyst & Ligand Development: Used as a starting material for synthesizing novel boron-containing catalysts or ligands for asymmetric synthesis.

Quality Control

Our production of this high-purity organoboron reagent adheres to stringent quality protocols. Every batch is characterized and tested to ensure identity, purity, and consistency, meeting the exacting standards required for research and process chemistry. A comprehensive Certificate of Analysis (COA) detailing results from NMR, HPLC, and other analytical methods is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent decomposition.
