Description

2-(3-Aminophenylsulfonyl)Ethanol is a versatile aromatic sulfonamide derivative with both amino and hydroxyl functional groups. This bifunctional nature makes it a valuable intermediate for synthesizing more complex molecules in advanced chemical manufacturing. It is primarily sought after by R&D and production teams in the pharmaceutical, agrochemical, and specialty chemical industries for creating active ingredients and functional materials.

Application

• Pharmaceutical Intermediate: Key building block for the synthesis of sulfonamide-based drugs, including diuretics and antimicrobial agents.
• Agrochemical Synthesis: Used in the production of herbicides and fungicides, leveraging its sulfonyl group for biological activity.
• Dye and Pigment Manufacturing: Serves as a precursor for azo dyes and other colorants due to its aromatic amine structure.
• Polymer Modification: Functional monomer for introducing sulfonamide and hydroxyl groups into polymer chains to alter solubility or reactivity.
• Cross-linking Agent: Utilized in epoxy resin systems and other thermosetting polymers.
• Research & Development: Valuable scaffold in medicinal chemistry for exploring new drug candidates and biochemical probes.

Quality Control

Our 2-(3-Aminophenylsulfonyl)Ethanol is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets precise specifications for use in sensitive applications. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance and regulatory compliance needs.

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 degradation from atmospheric moisture.
