Description

Diethyl(3-Pyridyl)Borane is a versatile organoboron reagent featuring a pyridyl group, making it a valuable building block in modern synthetic chemistry. Its primary value lies in its role as a coupling partner in Suzuki-Miyaura cross-coupling reactions, enabling the efficient construction of complex biaryl and heterobiaryl structures. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require precise, scalable methods for introducing pyridyl motifs into target molecules.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs) containing pyridine or bipyridine scaffolds.
• Agrochemical Synthesis: Used to create novel herbicides, fungicides, and insecticides with tailored properties.
• Ligand and Catalyst Development: Serves as a starting material for synthesizing sophisticated ligands used in homogeneous catalysis.
• Material Science Research: Employed in the development of organic electronic materials, such as OLEDs and conductive polymers.
• Cross-Coupling Reactions: A specialized boronic ester for Suzuki-Miyaura cross-coupling to form carbon-carbon bonds under mild conditions.
• Chemical Biology Probes: Useful for labeling and modifying biomolecules in drug discovery research.

Quality Control

Our Diethyl(3-Pyridyl)Borane is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity for sensitive applications. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing key parameters such as assay, identity, and impurity profiles. Our quality system is designed to support cGMP and ISO standards for customers in regulated industries.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (argon or nitrogen) at 2-8°C in a cool, dry, and well-ventilated place. Due to its highly volatile and hygroscopic nature, containers must be kept sealed and allowed to reach room temperature before opening to minimize moisture ingress and oxidation.
