Description

4-Carboxynaphthalene-1-Boronic Acid is a multifunctional aromatic building block that combines a carboxylic acid group with a boronic acid moiety on a naphthalene scaffold. This unique structure makes it a highly valuable intermediate for the synthesis of complex molecules, particularly in advanced material science and pharmaceutical research. It is primarily sought after by R&D chemists and process development scientists working on organic electronics, sensors, and active pharmaceutical ingredients (APIs).

Application

• Suzuki-Miyaura Cross-Coupling Reactions: A key reagent for constructing biaryl and conjugated systems in pharmaceutical and material chemistry.
• Organic Electronic Materials: Serves as a precursor for electron-transport materials, organic semiconductors, and light-emitting diodes (OLEDs).
• Pharmaceutical Intermediates: Used in the synthesis of protease inhibitors, kinase inhibitors, and other small-molecule drug candidates.
• Chemical Sensor Development: Functional component in the creation of fluorescent probes and molecular recognition systems for diagnostic applications.
• Metal-Organic Frameworks (MOFs): Building block for constructing porous coordination polymers with tailored properties for gas storage or catalysis.
• Polymer Chemistry: Monomer or cross-linking agent for synthesizing specialty polymers with unique thermal or mechanical properties.

Quality Control

Our 4-Carboxynaphthalene-1-Boronic Acid is produced under strict quality management protocols. Every batch undergoes rigorous analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure it meets the high standards required for research and development. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each 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). This compound is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent degradation.
