Description

3-Borono-5-Methoxybenzoic Acid is a high-purity boronic acid derivative that serves as a critical building block in modern synthetic chemistry. Its value lies in its dual functionality, combining a reactive boronic acid group with a carboxylic acid moiety, enabling precise cross-coupling and subsequent derivatization. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries, particularly for the synthesis of complex molecules and advanced materials.

Application

• Pharmaceutical Intermediate: A key precursor in Suzuki-Miyaura cross-coupling reactions for constructing biaryl structures found in active pharmaceutical ingredients (APIs).
• Agrochemical Synthesis: Used in the development of novel herbicides and fungicides that require specific aromatic frameworks.
• Material Science Research: Employed in the creation of organic ligands for metal-organic frameworks (MOFs) and other functional polymers.
• Chemical Biology Probes: Serves as a versatile handle for bioconjugation and the development of sensor molecules due to its orthogonal reactivity.
• Organic Electronics: Acts as a monomer or building block for conjugated systems used in OLEDs and organic semiconductors.
• Custom Synthesis & Contract Manufacturing: Supplied to CDMOs for the production of bespoke compounds and libraries for drug discovery.

Quality Control

Our 3-Borono-5-Methoxybenzoic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and FTIR, to ensure high chemical purity and identity confirmation. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all relevant specifications. Our quality commitment supports applications in GMP and ISO-compliant environments.

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 after opening to minimize exposure to atmospheric moisture. For long-term storage, consider using desiccants.
