Description

3,3'-(5-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)-1,3-Phenylene)Dipyridine is a high-purity, multi-functional organic building block featuring a central phenylene core flanked by pyridine rings and a key pinacol boronate ester group. This compound matters for its critical role as a versatile intermediate in modern synthetic chemistry, enabling precise carbon-carbon and carbon-heteroatom bond formation. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and materials science industries for constructing complex molecular architectures.

Application

• Pharmaceutical Intermediate: Key building block in Suzuki-Miyaura cross-coupling reactions for synthesizing active pharmaceutical ingredients (APIs) and drug candidates.
• Agrochemical Synthesis: Used in the development of novel herbicides, fungicides, and insecticides requiring specific bipyridine-based structures.
• Organic Light-Emitting Diodes (OLEDs): Serves as a precursor for electron-transport materials and emissive layer components in display and lighting technologies.
• Ligand Synthesis for Catalysis: Acts as a precursor for creating sophisticated bipyridine and terpyridine ligands used in homogeneous catalysis and coordination chemistry.
• Polymer & Material Science: Incorporated into conjugated polymers and metal-organic frameworks (MOFs) to tune electronic properties and porosity.
• Chemical Biology Probes: Utilized in the synthesis of molecular probes and tags for imaging and diagnostic applications.

Quality Control

Our 3,3'-(5-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)-1,3-Phenylene)Dipyridine is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and mass spectrometry, to ensure identity, purity, and consistency. Certificates of Analysis (COA) with detailed specifications are available upon request 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. Keep away from incompatible materials.
