Description

4-Ethoxy-3-Ethylphenylboronic Acid is a specialized organoboron compound, a key building block in modern synthetic chemistry. Its primary value lies in its role as a versatile coupling partner in Suzuki-Miyaura cross-coupling reactions, enabling the efficient construction of complex biaryl structures. This high-purity intermediate is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries, particularly in the development of novel active ingredients and advanced materials.

Application

• Pharmaceutical Intermediate: A critical precursor in the synthesis of active pharmaceutical ingredients (APIs) and drug candidates, especially those containing complex biaryl or heterobiaryl motifs.
• Agrochemical Synthesis: Used in the research and production of advanced herbicides, fungicides, and insecticides, where its structural motif can contribute to biological activity.
• Material Science: Serves as a building block for creating organic electronic materials, such as those used in OLEDs (Organic Light-Emitting Diodes) and semiconductors.
• Ligand & Catalyst Development: Employed in the preparation of novel ligands and organometallic catalysts for asymmetric synthesis and other catalytic processes.
• Chemical Research & Development: A valuable reagent for academic and industrial R&D labs exploring new synthetic methodologies and constructing molecular libraries for screening.
• Fine Chemical Production: Integral to the multi-step synthesis of complex fine chemicals and specialty compounds where precise carbon-carbon bond formation is required.

Quality Control

Our 4-Ethoxy-3-Ethylphenylboronic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and elemental analysis, to ensure high chemical purity and identity. Certificates of Analysis (COA) detailing purity, assay, and impurity profiles are provided with every shipment and are available upon request to support your quality assurance protocols.

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). This compound is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent degradation. Keep away from incompatible materials.
