Description

[3-(Cyclopentyloxy)Phenyl]Boranediol is a high-purity boronic acid derivative, specifically a boronic ester diol, serving as a critical synthetic intermediate in advanced organic chemistry. Its value lies in enabling precise Suzuki-Miyaura cross-coupling reactions, a cornerstone methodology for constructing complex biaryl and heterobiaryl scaffolds. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries developing novel active ingredients, as well as in materials science for creating specialized organic electronic components.

Application

• Pharmaceutical Intermediate: Key building block for synthesizing drug candidates, particularly those containing biphenyl or aryl-heteroaryl motifs.
• Agrochemical Synthesis: Used in the research and production of advanced herbicides, fungicides, and insecticides requiring specific aryl couplings.
• Material Science Research: Employed in the development of organic light-emitting diodes (OLEDs), semiconductors, and liquid crystals.
• Chemical Research & Development: A versatile reagent for academic and industrial R&D labs exploring new catalytic cross-coupling methodologies.
• Ligand Synthesis: Precursor for creating novel bidentate or tridentate ligands used in catalysis and metal-organic frameworks (MOFs).

Quality Control

Our [3-(Cyclopentyloxy)Phenyl]Boranediol is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and IR spectroscopy, to ensure high chemical purity and structural identity. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing all relevant specifications. Our quality commitment supports compliance with cGMP and ICH guidelines for use in regulated research and development.

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 nature, the container must be kept tightly sealed under an inert atmosphere (argon or nitrogen) to prevent moisture absorption and decomposition. Keep away from heat and incompatible materials.
