Description

Phenol, 3-Fluoro-, Monoester With Boric Acid (H3Bo3) (9Ci) CAS NO 274251-51-3 is a specialized organoboron compound that combines a fluorinated phenol moiety with boric acid. This unique structure makes it a valuable intermediate and reagent for advanced synthesis, particularly where the introduction of both fluorine and boron functionalities is required. It is primarily utilized by R&D chemists and process development scientists in the pharmaceutical and agrochemical industries for creating novel active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of novel drug candidates, especially those requiring fluorinated aromatic systems and Suzuki-Miyaura cross-coupling reactions.
• Agrochemical Synthesis: Used in the development of advanced pesticides and herbicides, where the fluorine atom enhances biological activity and metabolic stability.
• Material Science Precursor: Serves as a monomer or cross-linking agent in the production of specialty polymers and boron-containing resins with unique thermal or optical properties.
• Ligand and Catalyst Development: Employed in the creation of novel boron-based ligands for transition metal catalysis and asymmetric synthesis.
• Research & Development: A critical reagent in academic and industrial R&D labs for exploring new organoboron chemistry and fluorination methodologies.
• Electronic Chemicals: Potential use in the synthesis of materials for organic light-emitting diodes (OLEDs) and other electronic applications due to its conjugated system.

Quality Control

Our production of Phenol, 3-Fluoro-, Monoester With Boric Acid adheres to stringent quality protocols to ensure batch-to-batch consistency and high purity for sensitive synthetic applications. Each lot is characterized using advanced analytical techniques including NMR, HPLC, and elemental analysis. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles is provided with every shipment to support your quality assurance and regulatory documentation.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect purity and reactivity. Keep away from incompatible materials such as strong bases and oxidizing agents.
