Description

3-(Phenoxymethyl)Benzeneboronic Acid, Pinacol Ester is a protected boronic acid derivative, a crucial intermediate in modern synthetic organic chemistry. Its value lies in its enhanced stability compared to the free boronic acid, making it ideal for demanding synthetic protocols and long-term storage. This compound is primarily needed by research chemists and process development scientists in the pharmaceutical and agrochemical industries for constructing complex molecules via Suzuki-Miyaura cross-coupling reactions.

Application

• Pharmaceutical Intermediate: A key building block in the synthesis of active pharmaceutical ingredients (APIs) and drug candidates, particularly those containing biaryl motifs.
• Agrochemical Synthesis: Used in the research and development of novel herbicides, fungicides, and insecticides requiring specific aromatic couplings.
• Material Science Research: Serves as a monomer or precursor in the development of advanced organic electronic materials, such as polymers for OLEDs or OFETs.
• Ligand and Catalyst Development: Employed as a synthetic handle for creating novel ligands and organometallic catalysts.
• Chemical Biology Probes: Utilized in the synthesis of molecular probes and tags for studying biological systems.
• Custom Synthesis and Contract Manufacturing: A critical reagent for custom synthesis houses serving the life sciences sector.

Quality Control

Our 3-(Phenoxymethyl)Benzeneboronic Acid, Pinacol Ester is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR, HPLC, and GC, to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every 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 room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent moisture absorption and degradation.
