Description

4,4,5,5-Tetramethyl-2-[5-(1,1,2,2,3,3,4,4,5,5,6,6,6-Tridecafluorohexyl)-2-thienyl]-1,3,2-dioxaborolane is a high-value, fluorinated boronic ester derivative, serving as a critical building block in advanced material synthesis. Its core value lies in the unique combination of a reactive pinacol boronate ester group and a highly fluorinated alkyl chain, which imparts exceptional hydrophobicity, oleophobicity, and chemical resistance to final products. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and specialty polymer industries, particularly for applications requiring precise cross-coupling reactions and surface modification.

Application

• Suzuki-Miyaura Cross-Coupling Reactions: A key reagent for constructing complex biaryl and heteroaryl structures in pharmaceutical and agrochemical active ingredient development.
• Fluorinated Polymer Synthesis: Used as a monomer or chain-transfer agent to incorporate fluorinated segments, enhancing material properties like chemical inertness, thermal stability, and low surface energy.
• Surface Modification & Coatings: Enables the creation of hydrophobic and oleophobic surfaces for textiles, electronics, and medical devices.
• Liquid Crystal & OLED Material Development: Acts as a precursor for fluorinated organic semiconductors and liquid crystal molecules, improving device performance and stability.
• Catalyst & Ligand Design: Serves as a precursor for novel fluorinated ligands used in catalysis, particularly in reactions requiring specialized solvent environments.
• Organic Synthesis Intermediate: A versatile intermediate for introducing the 1,1,2,2,3,3,4,4,5,5,6,6,6-tridecafluorohexyl moiety into more complex molecular architectures.

Quality Control

Every batch of 4,4,5,5-Tetramethyl-2-[5-(1,1,2,2,3,3,4,4,5,5,6,6,6-Tridecafluorohexyl)-2-thienyl]-1,3,2-dioxaborolane is produced and analyzed under strict quality management protocols. Our products undergo rigorous quality testing, including advanced chromatographic and spectroscopic methods, to ensure high purity and batch-to-batch consistency suitable for research and scale-up applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles 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 a controlled 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 degradation. Keep away from heat, sparks, and open flame.
