  • Applications

    Aminoethyl sulfate (CAS 926-39-6) is used primarily as an amino-functionalization reagent and chemical intermediate. In industry, it is commonly employed as a building block for synthesizing amino-functional compounds, including cationic surfactants and polymer modifiers. It serves as a convenient source of primary amino groups for coupling reactions in various synthesis workflows. In coatings, inks, and adhesives, it can be used as a functional additive or building block that introduces amino functionality. Additionally, it may appear in cosmetic/personal-care ingredient streams where amino-functional additives are required, subject to regulatory compliance.
