Description

4-Formylphenylboronic Acid is a versatile bifunctional aromatic building block that combines a formyl group with a boronic acid moiety. This dual functionality makes it a critical intermediate in modern synthetic chemistry, particularly for constructing complex molecular architectures via sequential cross-coupling and condensation reactions. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and materials science industries developing advanced organic compounds.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of active pharmaceutical ingredients (APIs), especially in Suzuki-Miyaura cross-coupling reactions to create biaryl structures.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and insecticides that require specific aromatic frameworks.
• Ligand and Catalyst Preparation: Serves as a precursor for synthesizing sophisticated ligands used in homogeneous catalysis and metal-organic frameworks (MOFs).
• Polymer and Material Science: Employed in the creation of functionalized polymers, organic electronic materials, and advanced coatings.
• Chemical Biology Probes: Utilized in the design and synthesis of molecular probes and sensors for biochemical research.
• Custom Organic Synthesis: A fundamental reagent for contract research organizations (CROs) and fine chemical suppliers producing custom-synthesized compounds.

Quality Control

Our 4-Formylphenylboronic Acid is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including HPLC for purity and NMR for structural confirmation, to ensure it meets the high standards required for research and industrial synthesis. A Certificate of Analysis (COA) detailing specific results for purity, identity, and impurities is provided with every shipment to guarantee traceability and batch-to-batch consistency.

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 in a dry environment to prevent moisture absorption, which can affect product stability and performance.
