Description

2-(4-Aminophenylsulfonyl)Ethyl Cellulose is a chemically modified cellulose ether derivative, characterized by the introduction of an aminophenylsulfonyl functional group onto the ethyl cellulose backbone. This modification imparts unique properties, making it a valuable intermediate for advanced material synthesis and specialty polymer applications. It is primarily utilized by R&D laboratories and industrial manufacturers in the pharmaceutical, specialty coatings, and advanced material sectors seeking to develop products with tailored solubility, binding, or controlled-release characteristics.

Application

• Pharmaceutical Excipient Intermediate: Used in the research and development of novel drug delivery systems, such as enteric coatings and controlled-release matrix tablets.
• Specialty Polymer Synthesis: Serves as a functionalized polymer backbone for creating advanced materials with specific chemical reactivity or physical properties.
• Advanced Coating Formulations: Employed in the development of specialty coatings that require enhanced adhesion, chemical resistance, or specific surface characteristics.
• Chromatography Media: Can be utilized as a starting material or ligand support in the preparation of stationary phases for analytical or preparative chromatography.
• Bioconjugation and Immobilization: The reactive amino group facilitates its use in immobilizing enzymes, antibodies, or other biomolecules for diagnostic or catalytic applications.
• Adhesive and Sealant Modifier: Acts as a modifying agent to alter the rheology, tack, or curing properties of high-performance adhesives and sealants.

Quality Control

Our 2-(4-Aminophenylsulfonyl)Ethyl Cellulose is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. Certificates of Analysis (COA) detailing key parameters are provided and available upon request. We support compliance with relevant regulatory frameworks for research and industrial use.

Storage

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