Description

n-(2-Hydroxyethyl)Benzenesulfonamide is a versatile sulfonamide derivative characterized by a reactive hydroxyl group. This functional group makes it a valuable intermediate for the synthesis of specialty chemicals, offering opportunities for further chemical modification. It is primarily sought after by manufacturers in the pharmaceutical, agrochemical, and polymer industries for developing active ingredients, surfactants, and functional additives.

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 plant growth regulators.
• Polymer Modification: Acts as a monomer or cross-linking agent to introduce sulfonamide and hydroxyl functionalities into polymer chains, enhancing properties like hydrophilicity.
• Surfactant & Detergent Industry: Serves as a precursor for anionic surfactants with improved solubility and emulsifying characteristics.
• Dye & Pigment Manufacturing: Intermediate in the synthesis of specialty dyes and organic pigments.
• Research & Development: Utilized in academic and industrial R&D for exploring new chemical entities and reaction pathways.

Quality Control

Our n-(2-Hydroxyethyl)Benzenesulfonamide is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay (HPLC), identification (IR), and impurity profiling, to ensure it meets precise specifications. A Certificate of Analysis (COA) documenting purity, physical properties, and test results is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent absorption of atmospheric moisture, which may affect product quality.
