Description

5-Chloro-2-(Methoxycarbonyl)Phenylboronic Acid is a high-purity boronic acid derivative, a critical building block in modern synthetic organic chemistry. Its value lies in its dual functionality, combining a reactive boronic acid group with a protected carboxylic acid moiety, enabling precise cross-coupling reactions. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries developing new active ingredients, particularly for Suzuki-Miyaura coupling to create complex biaryl structures.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of active pharmaceutical ingredients (APIs) via Suzuki-Miyaura cross-coupling reactions.
• Agrochemical Synthesis: Used in the research and production of advanced herbicides, fungicides, and insecticides requiring specific biaryl scaffolds.
• Material Science Research: Serves as a monomer or building block for creating novel organic electronic materials, polymers, and liquid crystals.
• Chemical Biology & Probe Development: Utilized in the design and synthesis of molecular probes, sensors, and bioconjugates that leverage boronic acid chemistry.
• Catalyst Ligand Synthesis: Acts as a starting material for the preparation of sophisticated ligands used in homogeneous catalysis.
• Custom Synthesis & Contract Manufacturing: Supplied to CDMOs and research institutions for bespoke synthesis projects and library generation.

Quality Control

Every batch of 5-Chloro-2-(Methoxycarbonyl)Phenylboronic Acid is produced and tested under a strict quality management system. Our products undergo rigorous quality testing, including advanced chromatographic and spectroscopic methods, to ensure compliance with industry standards and customer specifications. Certificates of Analysis (COA) detailing purity, identity, and impurity profiles are available upon request.

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 to prevent moisture absorption, which can affect stability and reactivity. For long-term storage, consider using desiccants or an inert atmosphere.
