Description

5-Formylpyridine-3-Boronic Acid Pinacol Ester is a high-purity, multifunctional heterocyclic boronic ester building block essential for modern synthetic chemistry. This compound is particularly valued for its dual reactive sites—the formyl group and the protected boronic acid—enabling precise cross-coupling and subsequent functionalization reactions. It is a critical intermediate for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require reliable, high-quality reagents for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs) via Suzuki-Miyaura cross-coupling reactions.
• Agrochemical Synthesis: Used to create novel herbicides, fungicides, and insecticides with specific activity profiles.
• Ligand & Catalyst Development: Serves as a precursor for creating novel pyridine-based ligands for catalysis and metal-organic frameworks (MOFs).
• Material Science: Employed in the development of organic electronic materials, such as OLEDs and conductive polymers.
• Chemical Biology & Proteomics: Useful as a probe or linker molecule in bioconjugation and target identification studies.
• Academic & Process R&D: A versatile reagent for method development and exploring new synthetic pathways in research laboratories.

Quality Control

Our 5-Formylpyridine-3-Boronic Acid Pinacol Ester is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC, NMR, and LC-MS, to ensure high chemical purity and identity confirmation. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment to support your quality assurance and regulatory needs.

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 (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
