Description

5-Formylfuran-3-Boronic Acid Pinacol Ester is a high-value, multifunctional heterocyclic building block that combines a formyl group with a protected boronic acid moiety. This unique structure matters for its pivotal role in modern synthetic chemistry, enabling efficient cross-coupling reactions and serving as a versatile precursor for complex molecular architectures. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials industries for constructing novel compounds and fine chemicals.

Application

• Pharmaceutical Intermediate: A key precursor in Suzuki-Miyaura cross-coupling reactions for synthesizing novel drug candidates, particularly in medicinal chemistry programs targeting complex heterocycles.
• Agrochemical Synthesis: Used in the development of new active ingredients for crop protection, leveraging its boronic ester functionality for efficient carbon-carbon bond formation.
• Material Science Research: Serves as a building block for creating functionalized polymers, organic electronic materials, and metal-organic frameworks (MOFs) due to its reactive aldehyde and boronate groups.
• Chemical Biology & Probe Development: Employed in the synthesis of bioconjugates, fluorescent tags, and molecular probes where its formyl group allows for further functionalization via reductive amination or condensation.
• Catalyst Ligand Synthesis: Acts as a starting material for preparing sophisticated ligand systems used in asymmetric catalysis and transition metal complexes.
• Academic & Contract Research: Essential for exploratory research in synthetic methodology development and the construction of complex natural product analogs.

Quality Control

Our 5-Formylfuran-3-Boronic Acid Pinacol Ester is manufactured under strict quality management protocols. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and LC-MS, to ensure high purity and batch-to-batch consistency. Certificates of Analysis (COA) detailing identity, purity, and impurity profiles are provided with every shipment to support your quality assurance and regulatory documentation needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 2-8°C under an inert atmosphere (e.g., nitrogen or argon) due to its hygroscopic and moisture-sensitive nature. Allow the container to reach room temperature before opening to minimize moisture ingress.
