Description

3-Chloro-4-Propoxyphenylboronic Acid is a high-purity organoboron compound, specifically a boronic acid derivative, that serves as a critical 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 intermediate is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries engaged in the development of new active ingredients and advanced materials.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs) and drug candidates, particularly those containing biphenyl or heterobiaryl motifs.
• Agrochemical Synthesis: Used in the research and production of novel herbicides, fungicides, and insecticides that require specific aryl-aryl linkages.
• Material Science: Building block for creating organic electronic materials, such as those used in OLEDs and organic photovoltaics, where precise molecular architecture is crucial.
• Ligand and Catalyst Development: Serves as a starting material for synthesizing specialized ligands and catalysts used in asymmetric synthesis and other catalytic processes.
• Chemical Research & Development: A valuable reagent for academic and industrial R&D labs exploring new carbon-carbon bond-forming methodologies and library synthesis.

Quality Control

Our 3-Chloro-4-Propoxyphenylboronic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and elemental analysis, to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment, ensuring full traceability and compliance with your research or production requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
