Description

4-(Aminosulfonyl)Phenylboronic Acid is a high-value organoboron building block featuring both a boronic acid and a sulfonamide functional group. This bifunctional nature makes it a critical intermediate for synthesizing complex molecules via Suzuki-Miyaura cross-coupling reactions. It is essential for researchers and manufacturers in the pharmaceutical and agrochemical industries developing new active ingredients, particularly for creating sulfonamide-containing compounds.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel drug candidates, especially those incorporating sulfonamide pharmacophores for therapeutic applications.
• Agrochemical Synthesis: Used in the research and production of advanced pesticides and herbicides, leveraging its unique structure for bioactivity.
• Material Science Research: Serves as a monomer or cross-linking agent in the development of functional polymers and advanced organic materials.
• Chemical Biology Probes: Utilized in the creation of molecular probes and sensors due to the specific reactivity of the boronic acid group.
• Catalyst Ligand Precursor: Can be modified to create specialized ligands for transition metal catalysis in fine chemical synthesis.
• Custom Synthesis & Contract Manufacturing: A vital starting material for custom synthesis houses serving the life sciences sector.
