Description

Diethylborinic Acid is an organoboron compound that serves as a versatile reagent and synthetic intermediate. Its value lies in its ability to act as a boron source and a ligand in various catalytic and stoichiometric transformations, enabling the synthesis of complex molecules. This product is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require high-purity organoboron building blocks for cross-coupling reactions and polymer synthesis.

Application

• Pharmaceutical Intermediate: Used in the synthesis of active pharmaceutical ingredients (APIs), particularly in Suzuki-Miyaura cross-coupling reactions to form carbon-carbon bonds.
• Catalyst & Ligand Precursor: Serves as a precursor for generating catalysts and ligands in asymmetric synthesis and polymerization processes.
• Agrochemical Synthesis: Employed in the development of novel herbicides, fungicides, and plant growth regulators.
• Material Science: Acts as a key monomer or additive in the production of boron-containing polymers and advanced ceramic materials.
• Organic Synthesis Reagent: Utilized in hydroboration reactions and as a boronylating agent in laboratory-scale and industrial organic synthesis.
• Research & Development: A critical tool for chemical R&D in academic and industrial settings for exploring new organoboron chemistry.

Quality Control

Our Diethylborinic Acid is produced under stringent quality management protocols. Every batch undergoes comprehensive analytical testing, including NMR, GC, and titration, to ensure high chemical purity and consistency. We provide detailed Certificates of Analysis (COA) with each shipment, confirming compliance with agreed specifications. Our quality system supports traceability and meets the rigorous standards required for research and industrial applications.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area. Due to its sensitivity to oxidation, the container should be kept sealed and handled under an inert environment to maintain product integrity. Recommended storage temperature is 2-8°C for long-term stability.
