Description

4-[n-Cyclopropyl-n-(4-Methoxybenzyl)Sulfamoyl]Phenylboronic Acid is a high-purity, advanced pharmaceutical intermediate and a valuable building block in modern synthetic chemistry. Its core value lies in its dual functionality, combining a boronic acid group for Suzuki-Miyaura cross-coupling reactions with a complex sulfamoyl moiety, enabling the synthesis of sophisticated target molecules. This compound is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries, particularly in the development of new active ingredients and fine chemicals.

Application

• Pharmaceutical Intermediate: A key precursor in the synthesis of novel drug candidates, particularly those targeting specific enzyme pathways.
• Suzuki-Miyaura Cross-Coupling: Serves as a critical boronic acid coupling partner for constructing biaryl and heterobiaryl structures central to many active pharmaceutical ingredients (APIs).
• Agrochemical Research: Used in the development of new herbicides, fungicides, and insecticides with enhanced efficacy and selectivity.
• Material Science: Potential building block for creating functionalized polymers and advanced organic materials.
• Chemical Biology: Employed in the design and synthesis of molecular probes and inhibitors for biological target validation.
• Custom Synthesis & Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for client-specific synthesis projects.

Quality Control

Our 4-[n-Cyclopropyl-n-(4-Methoxybenzyl)Sulfamoyl]Phenylboronic Acid is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC for purity, NMR and IR for structural confirmation, and residual solvent analysis, to ensure it meets the high standards required for research and production. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee traceability and consistency.

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 (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) after opening to prevent degradation.
