Description

5-Chloro-2-Propoxyphenylboronic Acid is a versatile organoboron building block essential for modern synthetic chemistry. Its core value lies in enabling the efficient construction of complex molecules through pivotal cross-coupling reactions like the Suzuki-Miyaura reaction. This high-purity intermediate is critically needed by pharmaceutical R&D teams and fine chemical manufacturers developing active pharmaceutical ingredients (APIs), agrochemicals, and advanced materials.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of novel drug candidates, particularly in constructing biaryl and heterobiaryl scaffolds common in many therapeutic agents.
• Agrochemical Synthesis: Used in the development of advanced herbicides, fungicides, and insecticides that require specific chlorinated phenyl ether structures.
• Material Science Research: Serves as a monomer or building block for creating organic electronic materials, such as those used in OLEDs and organic photovoltaics.
• Ligand and Catalyst Development: Employed in the preparation of specialized ligands for transition metal catalysis and as a handle for immobilizing catalysts on solid supports.
• Chemical Biology Probes: Utilized in the synthesis of molecular probes and tags for studying biological processes and target engagement.
• Custom Synthesis & Contract Manufacturing: A critical raw material for CROs and CDMOs offering bespoke chemical synthesis services to the life sciences industry.

Quality Control

Every batch of our 5-Chloro-2-Propoxyphenylboronic Acid is manufactured and tested under a strict quality management system. We guarantee high chemical purity and lot-to-lot consistency, which is critical for reproducible results in sensitive cross-coupling applications. Our standard quality commitment includes comprehensive analytical characterization, and a detailed Certificate of Analysis (COA) with HPLC purity, NMR, and other relevant data is provided with each shipment.

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). This compound is hygroscopic (moisture-sensitive) and must be kept under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to prevent degradation. Keep away from heat and incompatible materials.
