Description

2-Bromo-5-(Ethylsulfonyl)Aniline is a high-purity, functionalized aniline derivative characterized by its bromo and ethylsulfonyl substituents. This compound serves as a versatile and critical pharmaceutical intermediate and organic synthesis building block, enabling the construction of complex molecules. It is primarily utilized by R&D chemists and process development scientists in the pharmaceutical, agrochemical, and advanced materials sectors for the synthesis of active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of novel drug candidates, particularly those targeting central nervous system (CNS) disorders, oncology, and inflammatory diseases.
• Agrochemical Synthesis: Used in the research and development of new herbicides, fungicides, and insecticides, leveraging its reactive aniline and sulfone functionalities.
• Material Science: Serves as a precursor for functional polymers, dyes, and liquid crystals where the bromine atom allows for further cross-coupling reactions.
• Organic Synthesis Reagent: Employed in palladium-catalyzed cross-coupling reactions (e.g., Suzuki, Buchwald-Hartwig) to introduce complex aniline motifs into target molecules.
• Chemical Research: Valuable reference standard and starting material in academic and industrial laboratories for methodological development and exploration of new chemical space.
