Description

Benzo[B]Naphtho[1,2-D]Furan, 3-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)- is a high-purity, advanced organic building block featuring a fused naphthofuran core and a pinacol boronate ester functional group. This compound matters as a critical intermediate in modern synthetic chemistry, enabling precise carbon-carbon bond formation via Suzuki-Miyaura cross-coupling reactions. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and materials science industries who require reliable, high-quality precursors for developing novel active ingredients and functional organic materials.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of complex drug candidates, particularly those with fused polycyclic aromatic structures.
• Agrochemical Synthesis: Used in the research and development of new herbicides, fungicides, and insecticides requiring specific aromatic frameworks.
• Organic Light-Emitting Diodes (OLEDs): Serves as a precursor for constructing novel electron-transporting or emitting materials in display and lighting technologies.
• Polymer & Materials Science: Enables the incorporation of rigid, planar aromatic units into polymers and advanced organic materials to tune electronic and mechanical properties.
• Ligand & Catalyst Development: Utilized in the preparation of sophisticated ligands for catalysis and metal-organic frameworks (MOFs).
• Academic & Industrial R&D: A valuable reagent for methodological development in cross-coupling chemistry and the exploration of new chemical space.

Quality Control

Our Benzo[B]Naphtho[1,2-D]Furan, 3-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)- is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and MS, to ensure high chemical purity and structural integrity. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are provided with each shipment to support your quality assurance and regulatory needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place. Due to its hygroscopic (moisture-sensitive) nature, it is recommended to handle and store the product under an inert atmosphere (e.g., nitrogen or argon) for long-term stability. Recommended storage temperature: 2-8°C for prolonged storage; allow to equilibrate to room temperature before opening to prevent moisture condensation.
