Description

Phenol, 4-Fluoro-, Monoester With Boric Acid (H3Bo3) (9Ci) is a specialized organoboron compound that combines a fluorinated phenol moiety with boric acid. This unique structure makes it a valuable intermediate and reagent in advanced synthetic chemistry, offering precise control in reactions where boron's Lewis acidity and fluorine's electronic effects are desired. It is primarily sought by R&D chemists and process development teams in the pharmaceutical, agrochemical, and advanced materials sectors for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for boron-containing drug candidates.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and insecticides where the fluorophenol-borate structure imparts specific biological activity.
• Polymer & Material Science: Serves as a monomer or cross-linking agent in the production of specialty polymers, resins, and flame-retardant materials.
• Liquid Crystal & OLED Materials: Acts as a precursor for electronic chemicals used in display and lighting technologies.
• Laboratory Reagent: Employed in academic and industrial research for Suzuki-Miyaura and other palladium-catalyzed cross-coupling reactions.
• Complexation Agent: Utilized in analytical chemistry and catalysis for its ability to form stable complexes with various metals and diols.

Quality Control

Every batch of Phenol, 4-Fluoro-, Monoester With Boric Acid is produced and tested under a strict quality management system. We provide comprehensive analytical data to ensure the material meets your precise research or production requirements. A Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is supplied with each shipment, confirming compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area 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.
