Description

2,5-Dichloro-4-Methoxyphenylboronic Acid is a high-value organoboron building block essential for modern synthetic chemistry. This compound matters for its role as a key coupling partner in Suzuki-Miyaura cross-coupling reactions, enabling the efficient construction of complex biaryl structures. It is primarily needed by research scientists and process chemists in the pharmaceutical, agrochemical, and advanced materials industries for developing new active ingredients and functional molecules.

Application

• Pharmaceutical Intermediate: A critical precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those containing complex, substituted biphenyl or heterobiaryl scaffolds.
• Agrochemical Synthesis: Used in the research and development of novel herbicides, fungicides, and insecticides where specific chlorinated and methoxylated aromatic systems are required for bioactivity.
• Material Science Research: Serves as a building block for creating organic electronic materials, such as those used in OLEDs (Organic Light-Emitting Diodes) and organic photovoltaics.
• Ligand and Catalyst Development: Employed in the preparation of specialized ligands for metal catalysis or as a core structure in catalyst design.
• Chemical Biology & Probe Synthesis: Utilized for constructing molecular probes and tags for studying biological processes and target engagement.
• Custom Synthesis & Contract Manufacturing: A vital reagent for custom synthesis organizations (CSOs) and CDMOs (Contract Development and Manufacturing Organizations) serving global clients.

Quality Control

Every batch of 2,5-Dichloro-4-Methoxyphenylboronic Acid is produced and tested under a strict quality management system. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request, providing detailed results for purity, identity, and impurity profiles to support your regulatory and R&D 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). This material is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and under an inert atmosphere (e.g., nitrogen or argon) for long-term storage to maintain optimal purity and reactivity.
