Description

4-(Ethylamino)Butane-1-Sulfonic Acid is a specialized organic sulfonic acid derivative featuring both an amino and a sulfonic acid functional group. This unique bifunctional structure makes it a valuable intermediate and building block for the synthesis of more complex molecules, particularly in the development of specialty surfactants, pharmaceutical actives, and high-performance additives. It is primarily sought by R&D chemists and process engineers in the fine chemical, pharmaceutical, and advanced material sectors. The compound is supplied to meet the stringent quality requirements of industrial and research applications.

Application

• Pharmaceutical Intermediate: Key building block in the synthesis of active pharmaceutical ingredients (APIs), especially those requiring sulfonate or taurine-like moieties for enhanced solubility or biological activity.
• Specialty Surfactant Synthesis: Serves as a precursor for the production of novel amphoteric or zwitterionic surfactants used in personal care, cosmetics, and high-performance cleaning formulations.
• Biochemical Research: Used as a buffer component or a modifying agent in biochemical assays and protein studies due to its buffering capacity near physiological pH.
• Polymer & Material Science: Employed as a monomer or additive to introduce sulfonic acid groups into polymers, improving hydrophilicity, ion-exchange capacity, or anti-static properties.
• Electroplating & Metal Treatment: Acts as a brightening agent or complexing agent in electroplating baths and surface treatment processes for metals.
• Catalysis & Ligand Synthesis: Useful for preparing chelating ligands or organocatalysts where the amino and sulfonic acid groups can coordinate to metals or participate in catalytic cycles.

Quality Control

Every batch of 4-(Ethylamino)Butane-1-Sulfonic Acid is manufactured and tested under a strict quality management system. We employ advanced analytical techniques including HPLC, NMR, and titration to ensure identity, purity, and consistency meet the high standards required for research and industrial synthesis. A comprehensive Certificate of Analysis (COA) detailing all test results is provided with each shipment to guarantee traceability and compliance with your specifications.

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 and stability.
