Description

Ethyl 2-Aminoethanesulfonate is an organosulfur compound featuring both an amino and an ester functional group. This unique structure makes it a valuable intermediate for the synthesis of more complex molecules, particularly in pharmaceutical and agrochemical research. It is primarily sought by chemical manufacturers and R&D laboratories for its role in creating sulfonamide derivatives and other functionalized compounds. Consistent quality and reliable supply are critical for its effective use in downstream synthesis.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), particularly those containing sulfonamide moieties.
• Agrochemical Synthesis: Used in the research and development of novel herbicides, fungicides, and plant growth regulators.
• Bioconjugation & Linker Chemistry: Serves as a reagent for modifying biomolecules or creating cleavable linkers in drug delivery systems and diagnostic probes.
• Organic Synthesis Reagent: Employed as a precursor for introducing the 2-aminoethanesulfonic acid (taurine) backbone or its ester derivatives into target molecules.
• Material Science Research: Investigated for the preparation of functional polymers and surfactants with specific ionic or hydrophilic properties.
• Chemical Research & Development: A versatile intermediate for academic and industrial research exploring new synthetic methodologies and compound libraries.

Quality Control

Our Ethyl 2-Aminoethanesulfonate is produced under a strict quality management system. Each batch undergoes comprehensive analytical testing, including chromatographic purity assays and identity confirmation, to ensure it meets the high standards required for research and synthesis. A Certificate of Analysis (COA) detailing specific results for purity, appearance, and other critical parameters is provided with every shipment to guarantee traceability and batch-to-batch consistency.

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). This product is hygroscopic (moisture-sensitive); ensure the container is kept tightly sealed to prevent absorption of atmospheric moisture, which may affect quality.
