Description

4-Boronophthalic Acid (CAS NO 1072946-35-0) is a high-value boronic acid derivative that serves as a critical building block in modern synthetic chemistry. Its primary importance lies in its dual functionality, combining a reactive boronic acid group with a phthalic acid moiety, making it an essential precursor for Suzuki-Miyaura cross-coupling reactions. This compound is particularly sought after by research institutions and manufacturers in the pharmaceutical and advanced materials sectors for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: A key synthon for the synthesis of active pharmaceutical ingredients (APIs), especially those containing complex aromatic and heterocyclic structures.
• Organic Light-Emitting Diodes (OLEDs): Used in the development of novel electron-transport materials and host materials for emissive layers.
• Ligand Synthesis: Serves as a precursor for creating sophisticated ligands used in catalysis and metal-organic frameworks (MOFs).
• Polymer Chemistry: Incorporated into specialty polymers to modify thermal stability, optical properties, or to introduce functional handles for further modification.
• Chemical Research: Employed in academic and industrial R&D for exploring new C-C bond formation methodologies and constructing molecular libraries.
• Sensor Development: Utilized in the fabrication of chemical sensors due to the selective binding properties of the boronic acid group.

Quality Control

Our 4-Boronophthalic Acid is manufactured under strict quality management protocols. Each batch undergoes comprehensive analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure it meets the high standards required for sensitive synthetic applications. A Certificate of Analysis (COA) detailing specific results for purity, identity, and impurity profiles is provided with every shipment.

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