Description

n-(4,5-Dichloro-2-Nitro-Phenyl)Benzenesulfonamide CAS NO 1596-36-7 is a specialized organic intermediate featuring a sulfonamide functional group attached to a dichloronitrophenyl moiety. This compound is valued for its role as a key building block in the synthesis of more complex molecules, particularly in advanced pharmaceutical and agrochemical research. It is primarily sought by R&D chemists and process development scientists in the fine chemical and active pharmaceutical ingredient (API) manufacturing sectors for constructing novel sulfonamide-based compounds.

Application

• Pharmaceutical Intermediate: A critical precursor in the synthesis of novel sulfonamide-based drug candidates, potentially for antimicrobial, anti-inflammatory, or enzyme-inhibiting therapies.
• Agrochemical Research: Serves as a building block for developing new herbicides, fungicides, or insecticides, leveraging the bioactivity of the sulfonamide and nitroaromatic groups.
• Dye and Pigment Synthesis: Used in the production of specialized azo dyes and organic pigments, where the nitro and chloro substituents influence color and stability.
• Material Science Research: Employed in the development of advanced polymers or functional materials that incorporate sulfonamide units for specific chemical properties.
• Chemical Biology Probes: Utilized as a scaffold for creating molecular probes to study enzyme function or protein interactions in biochemical research.
