Description

9-Phenanthreneboronic Acid Neopentylglycol Ester is a high-purity, protected boronic acid derivative essential for advanced organic synthesis. This compound matters as a critical building block in cross-coupling reactions, offering enhanced stability and handling characteristics compared to its free boronic acid counterpart. It is primarily needed by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and materials science industries for constructing complex polycyclic aromatic frameworks.

Application

• Suzuki-Miyaura Cross-Coupling Reactions: A key reagent for the palladium-catalyzed formation of carbon-carbon bonds, enabling the synthesis of novel phenanthrene-based compounds.
• Pharmaceutical Intermediate: Used in the research and development of active pharmaceutical ingredients (APIs) with polycyclic aromatic structures, potentially for anticancer or antiviral applications.
• Material Science Research: Serves as a precursor for organic electronic materials, such as organic light-emitting diodes (OLEDs) and semiconductors, where phenanthrene units can influence charge transport properties.
• Agrochemical Synthesis: Employed in creating novel herbicide or fungicide candidates that incorporate the phenanthrene moiety.
• Ligand and Catalyst Development: Useful for synthesizing complex ligands for catalysis or as a scaffold in metal-organic frameworks (MOFs).
• Chemical Biology Probes: Can be utilized to create molecular probes for studying biological processes due to its derivatizable boronate ester functionality.

Quality Control

Our 9-Phenanthreneboronic Acid Neopentylglycol Ester is manufactured under strict quality control protocols to ensure batch-to-batch consistency and high purity for sensitive synthetic applications. Each lot is characterized by NMR (1H, 13C, 11B), HPLC, and mass spectrometry. Certificates of Analysis (COA) detailing purity, identity, 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 or as indicated on the label. This material is hygroscopic (moisture-sensitive) and should be handled under an inert atmosphere (e.g., nitrogen or argon) when possible to maintain stability and prevent hydrolysis of the boronic ester.
