Description

1-(4-Bromophenyl)-n-Ethylmethanesulfonamide is a specialized organic intermediate featuring a bromophenyl group and a sulfonamide moiety. This compound is valued for its role as a key building block in the synthesis of more complex molecules, particularly in pharmaceutical and agrochemical research. It is primarily sought by R&D chemists and process development scientists working in medicinal chemistry and fine chemical manufacturing.

Application

• Pharmaceutical Intermediate: Serves as a crucial precursor in the synthesis of active pharmaceutical ingredients (APIs), particularly those targeting neurological or metabolic disorders.
• Agrochemical Research: Used in the development of novel herbicides, fungicides, and insecticides, leveraging the bioactivity of the sulfonamide functional group.
• Material Science: Acts as a monomer or additive in the production of advanced polymers with specific thermal or chemical resistance properties.
• Chemical Synthesis: Employed in cross-coupling reactions, such as Suzuki or Buchwald-Hartwig animations, facilitated by the reactive bromine atom.
• Ligand & Catalyst Development: Utilized in academic and industrial research to create novel ligands for metal catalysis or organocatalysts.
• Life Sciences Research: Functions as a biochemical tool or probe in proteomics and enzyme inhibition studies.

Quality Control

Our 1-(4-Bromophenyl)-n-Ethylmethanesulfonamide is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and GC-MS, to ensure identity, purity, and consistency. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with every shipment to guarantee compliance with your research and development requirements.

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 after each use to prevent degradation from atmospheric moisture.
