Description

1,3,4-Oxadiazole, 2,5-Bis[4-(4,4,5,5-Tetramethyl-1,3,2-Dioxaborolan-2-Yl)Phenyl]- is a high-purity, functionalized organic building block featuring a central 1,3,4-oxadiazole core flanked by two pinacol boronate ester groups. This compound is specifically engineered for advanced cross-coupling reactions, serving as a critical precursor in the synthesis of complex organic electronic materials and pharmaceutical intermediates. It is essential for R&D chemists and process engineers in the organic electronics, pharmaceutical, and agrochemical sectors who require reliable, high-quality boron reagents for Suzuki-Miyaura and other palladium-catalyzed coupling protocols.

Application

Quality Control

Every batch of our 1,3,4-Oxadiazole boronate ester is synthesized and purified under controlled conditions to ensure exceptional lot-to-lot consistency and reliability for sensitive cross-coupling applications. Our products undergo rigorous quality testing, including advanced chromatographic and spectroscopic methods, to ensure compliance with stringent internal specifications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request 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 a controlled room temperature (15-25°C). This material is moisture-sensitive (hygroscopic) and should be handled under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to maintain reactivity and purity. Keep away from strong oxidizers.
