Description

Benzo[B]Thiophen-4-Ylboronic Acid Pinacol Ester is a high-purity organoboron reagent, specifically a boronic ester derivative, essential for modern synthetic chemistry. Its core value lies in enabling efficient and selective carbon-carbon bond formation via Suzuki-Miyaura cross-coupling reactions. This compound is a critical building block for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors, where it is used to construct complex heterocyclic scaffolds.

Application

• Pharmaceutical Intermediate: A key synthon in the synthesis of novel active pharmaceutical ingredients (APIs), particularly those containing benzothiophene or related heterocyclic cores.
• Agrochemical Research: Used in the development of new herbicides, fungicides, and insecticides by facilitating the construction of complex molecular architectures.
• Material Science: Serves as a precursor in the creation of organic electronic materials, such as organic light-emitting diodes (OLEDs) and semiconductors.
• Chemical Synthesis: Enables Suzuki-Miyaura cross-coupling reactions to form biaryl and heterobiaryl structures with high efficiency and functional group tolerance.
• Ligand & Catalyst Development: Utilized in the preparation of novel ligands and organometallic catalysts for asymmetric synthesis.
• Life Sciences & Diagnostics: Acts as a building block for fluorescent probes, biomarkers, and other molecular tools used in biochemical research.

Quality Control

Our Benzo[B]Thiophen-4-Ylboronic Acid Pinacol Ester is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and GC-MS, to ensure high chemical purity and identity confirmation. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are provided with every shipment to guarantee batch-to-batch consistency and compliance with your research or production specifications.

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 the material under an inert atmosphere (e.g., nitrogen or argon) for long-term storage and to minimize exposure to ambient humidity. Recommended storage temperature is 2-8°C for optimal stability.
