Electro Plating, High-Purity Solvents

Hydropropyl Ethylene Diamine

N,N,N’,N’-Tetrakis(2-hydroxypropyl)ethylenediamine, identified by CAS number 102-60-3 and often marketed under the trade name Quadrol, is a versatile amino alcohol used extensively across several industrial sectors. This viscous, colorless to pale yellow liquid is a tertiary amine functionalized with four hydroxyl groups, providing it with unique cross-linking and neutralizing capabilities. Chemically, it acts as a high-performance polyol, frequently employed in the production of rigid polyurethane foams and elastomers where it enhances structural integrity. Its alkanolamine nature allows it to serve as an effective chelating agent for metal ions, particularly in electroless copper plating processes. Beyond industrial manufacturing, its exceptional stability and mildness make it a staple ingredient in the personal care industry, where it functions as a pH adjuster and stabilizer in various cosmetic formulations. Its multifunctional molecular architecture ensures it remains a critical component in advanced chemical synthesis, polymer science, and specialty coating applications globally, balancing reactivity with physical performance.
