Description

Diethyl(3-Formylphenyloxy)Borane is a specialized organoboron compound featuring a formylphenoxy ligand, which imparts unique reactivity. This compound matters as a versatile intermediate in advanced organic synthesis, particularly for constructing complex molecules through Suzuki-Miyaura cross-coupling and other transition metal-catalyzed reactions. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and materials science industries for creating novel active ingredients and functional polymers.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), especially those requiring aryl-boron motifs for cross-coupling.
• Agrochemical Synthesis: Used in the research and development of novel herbicides, fungicides, and insecticides that incorporate complex aromatic structures.
• Materials Science Research: Serves as a precursor for creating boron-containing polymers, liquid crystals, and organic electronic materials.
• Catalyst Ligand Development: The formylphenoxy group can be modified to develop novel ligands for homogeneous catalysis.
• Academic & Industrial R&D: A valuable reagent for methodological development in organic synthesis and exploring new boron chemistry.
• Fine Chemical Production: Employed in the multi-step synthesis of specialty chemicals and complex fragrance molecules.

Quality Control

Our Diethyl(3-Formylphenyloxy)Borane is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR (¹H, ¹¹B, ¹³C), HPLC for purity assessment, and Karl Fischer titration for moisture content, to ensure it meets the high standards required for research and process chemistry. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every 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 and highly volatile nature, the container must be kept tightly sealed under an inert atmosphere (argon or nitrogen) when not in use to prevent moisture absorption and decomposition. Keep away from heat, sparks, and open flame.
