Description

Boronic Acid, (4,5-Diethoxy-1-Naphthalenyl)- (9Ci) is a specialized naphthalene-based boronic acid derivative, 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 and heterobiaryl structures. This high-purity intermediate is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries, particularly in the development of new active ingredients and advanced materials.

Application

• Pharmaceutical Intermediate: A critical precursor in the synthesis of novel drug candidates, especially those containing complex naphthalene-based scaffolds.
• Agrochemical Synthesis: Used in the research and production of advanced pesticides and herbicides requiring specific biaryl linkages.
• Material Science: Serves as a monomer or building block for creating organic electronic materials, such as those used in OLEDs and organic photovoltaics.
• Chemical Research: A valuable reagent in academic and industrial R&D for methodology development and library synthesis in medicinal chemistry.
• Ligand Synthesis: Can be utilized to prepare sophisticated boronic acid-based ligands for catalysis and sensor applications.
• Cross-Coupling Reactions: Primarily employed in palladium-catalyzed Suzuki-Miyaura reactions to form carbon-carbon bonds with high efficiency and selectivity.

Quality Control

Our Boronic Acid, (4,5-Diethoxy-1-Naphthalenyl)- (9Ci) is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC for assay and impurity profiling, NMR for structural confirmation, and KF titration for moisture content. A detailed Certificate of Analysis (COA) is provided with every shipment, documenting all critical quality attributes.

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 nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation. Keep away from heat and incompatible materials.
