Description

4-Chloro-n-(2-Hydroxyethyl)Benzenesulfonamide is a versatile sulfonamide derivative characterized by its chloro-substituted aromatic ring and a polar hydroxyethyl side chain. This molecular structure makes it a valuable chemical intermediate for synthesizing more complex molecules, particularly in the pharmaceutical and agrochemical sectors. It is primarily sought by R&D chemists and process development teams in fine chemical, pharmaceutical, and specialty chemical manufacturing.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly for sulfonamide-based drugs.
• Agrochemical Synthesis: Used in the production of herbicides, fungicides, and other crop protection agents.
• Dye and Pigment Manufacturing: Serves as a precursor in the creation of specialized dyes and colorants.
• Polymer Modification: Acts as a functional monomer or additive to impart specific properties like hydrophilicity or reactivity to polymers.
• Research & Development: A crucial reagent in organic synthesis and medicinal chemistry research for exploring new chemical entities.
• Cross-coupling Reactions: The chloro group makes it a suitable substrate for various palladium-catalyzed coupling reactions.
