Description

3,5-Dicarboxybenzeneboronic Acid is a multifunctional aromatic boronic acid derivative that serves as a versatile building block in advanced organic synthesis. Its unique structure, featuring both boronic acid and carboxylic acid functional groups, makes it a critical intermediate for constructing complex molecules with precise spatial and electronic properties. This compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and materials science industries, particularly for applications in Suzuki-Miyaura cross-coupling reactions and the development of metal-organic frameworks (MOFs) or covalent organic polymers (COPs).

Application

• Pharmaceutical Intermediate: Key building block for synthesizing active pharmaceutical ingredients (APIs) and drug candidates via Suzuki-Miyaura cross-coupling, enabling the formation of biaryl structures.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and insecticides that require specific aromatic architectures.
• Materials Science: Serves as a linker or monomer for constructing advanced materials such as Metal-Organic Frameworks (MOFs), Covalent Organic Frameworks (COFs), and organic electronic polymers.
• Chemical Research & Development: A valuable reagent in academic and industrial R&D for exploring new catalytic processes and functional materials.
• Sensor Development: Utilized in the creation of boronic acid-based sensors for the detection of diols, sugars, and other analytes.
• Ligand Synthesis: Acts as a precursor for chelating ligands used in catalysis and metal complexation.

Quality Control

Our 3,5-Dicarboxybenzeneboronic Acid is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. Each lot undergoes comprehensive analytical testing, including HPLC, NMR, and elemental analysis, to verify identity, potency, and impurity profiles. A Certificate of Analysis (COA) detailing all specifications is provided with every shipment. We adhere to cGMP principles where applicable to support our customers in regulated industries.

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). This compound is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) when not in use to prevent degradation. Keep away from incompatible materials such as strong oxidizing agents.
