Description

3-Chlorophenyl 4-Boronobenzenesulfonamide is a specialized organoboron compound featuring a sulfonamide linker, making it a valuable bifunctional building block. This compound matters for its dual functionality, combining the electrophilic character of the aryl chloride with the nucleophilic reactivity of the boronic acid/sulfonamide group, enabling complex molecular construction. It is primarily needed by researchers and process chemists in the pharmaceutical and agrochemical industries for applications in Suzuki-Miyaura cross-coupling reactions and as a precursor in medicinal chemistry programs.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of novel active pharmaceutical ingredients (APIs) and drug candidates, particularly in oncology and CNS research.
• Suzuki-Miyaura Cross-Coupling Reagent: Serves as a versatile boronic acid derivative for forming carbon-carbon bonds to create complex biaryl structures.
• Agrochemical Synthesis: Used in the research and development of new herbicides, fungicides, and insecticides.
• Material Science Research: A precursor for developing advanced organic electronic materials and metal-organic frameworks (MOFs).
• Chemical Biology Probe Development: Utilized in creating targeted molecular probes for studying enzyme function and protein interactions.
• Custom Synthesis & Contract Manufacturing: Supplied to CDMOs for the production of bespoke compounds and library synthesis.
