Description

Benzo[B]Thien-2-Ylboronic Acid is a high-purity organoboron compound, specifically a boronic acid derivative of benzothiophene. This chemical serves as a critical synthetic intermediate, valued for its role in facilitating Suzuki-Miyaura cross-coupling reactions to construct complex heterocyclic systems. It is primarily utilized by research chemists and process development scientists in the pharmaceutical and advanced materials sectors for the synthesis of novel active pharmaceutical ingredients (APIs) and functional organic molecules.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of novel drug candidates, particularly those containing the benzothiophene scaffold.
• Suzuki-Miyaura Cross-Coupling: Essential reagent for forming carbon-carbon bonds between aryl/heteroaryl groups in medicinal chemistry and materials science research.
• Organic Light-Emitting Diodes (OLEDs): Used in the development of electron-transporting or emissive layer materials for display and lighting technologies.
• Agrochemical Research: Intermediate for creating new compounds with potential herbicidal or insecticidal activity.
• Ligand Synthesis: Precursor for creating specialized ligands used in catalysis and metal-organic frameworks (MOFs).
• Polymer Chemistry: Building block for incorporating the benzothiophene unit into conjugated polymers for electronic applications.

Quality Control

Our Benzo[B]Thien-2-Ylboronic Acid is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC, NMR, and elemental analysis, to ensure high purity and consistency. Certificates of Analysis (COA) detailing batch-specific results are provided and available upon request, supporting your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container should be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation. Recommended long-term storage temperature is 2-8°C.
