Description

3-Methyl-4-(Ethoxycarbonyl)Phenylboronic Acid is a high-purity boronic acid derivative, a crucial building block in modern synthetic organic chemistry. Its primary value lies in its role as a key intermediate in the Suzuki-Miyaura cross-coupling reaction, enabling the efficient formation of carbon-carbon bonds. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require precise and reliable synthetic intermediates for developing new active ingredients and functional molecules.

Application

• Pharmaceutical Intermediate: A critical precursor in the synthesis of complex drug candidates, particularly those requiring biaryl or heterobiaryl motifs via Suzuki-Miyaura cross-coupling.
• Agrochemical Synthesis: Used in the research and development of novel herbicides, fungicides, and insecticides where the introduction of the substituted phenylboronic acid moiety is required.
• Ligand and Catalyst Development: Serves as a starting material for creating specialized ligands and organometallic catalysts used in asymmetric synthesis and other catalytic processes.
• Material Science Research: Employed in the construction of organic electronic materials, such as those for OLEDs (Organic Light-Emitting Diodes) and conductive polymers.
• Chemical Biology & Proteomics: Can be utilized in the development of chemical probes and affinity reagents that target specific proteins or biological pathways.
• Custom Synthesis and Contract Manufacturing: A vital component for custom synthesis houses and CROs (Contract Research Organizations) serving the global chemical industry.

Quality Control

Every batch of 3-Methyl-4-(Ethoxycarbonyl)Phenylboronic Acid is manufactured under strict quality management protocols. Our products undergo rigorous analytical testing, including HPLC, NMR, and FTIR, to ensure high purity and consistent batch-to-batch quality suitable for demanding synthetic applications. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with each shipment to support your quality assurance and regulatory needs.

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 easily oxidized nature, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term preservation and to minimize degradation.
