(S,S)-Ethylenediamine-N,N-disuccinic acid sodium salt (EDDS-Na) (Cat No.: M041689) is a biodegradable, chiral chelating agent derived from ethylenediamine and succinic acid, with sodium counterions enhancing water solubility. Unlike conventional chelators like EDTA, EDDS is environmentally friendly and exhibits high affinity for metal ions such as iron, copper, and zinc. It is widely used in detergents, water treatment, and soil remediation to sequester heavy metals. The (S,S)-stereoisomer provides superior biodegradability and selective metal binding, making it ideal for sustainable chemical applications and eco-safe formulations.
