Description

2,4-Dichloro-5-(Cyclopentyloxy)Phenylboronic Acid is a specialized boronic acid derivative that serves as a critical building block in modern synthetic chemistry. Its value lies in its role as a versatile coupling partner in Suzuki-Miyaura cross-coupling reactions, enabling the efficient construction of complex biaryl and heterobiaryl structures. This high-purity intermediate is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries, particularly in the development of novel active ingredients and advanced materials.

Application

• Pharmaceutical Intermediate: Key precursor in the synthesis of active pharmaceutical ingredients (APIs) and drug candidates, especially those containing complex biphenyl scaffolds.
• Agrochemical Synthesis: Used in the research and production of advanced herbicides, fungicides, and insecticides requiring specific halogenated aryl structures.
• Material Science: Building block for creating organic electronic materials, liquid crystals, and polymers via palladium-catalyzed cross-coupling reactions.
• Chemical Research & Development: A valuable reagent in academic and industrial R&D labs for constructing compound libraries and exploring new synthetic pathways.
• Ligand Synthesis: Serves as a precursor for synthesizing specialized ligands used in catalysis and coordination chemistry.

Quality Control

Our 2,4-Dichloro-5-(Cyclopentyloxy)Phenylboronic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and elemental analysis, to ensure high chemical purity and consistent performance. A comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles is provided with every shipment to support your quality assurance protocols.

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 (e.g., nitrogen or argon) to prevent moisture absorption and degradation.
