Tetraacetylethylenediamine

Tetraacetylethylenediamine (TAED) is an organic chemical compound. Its chemical formula is 101642, or (CH3CO)2N-CH2CH2-N(COCH3)2. It is white, but the manufactured form comes in crystals dyed blue or green.

Its CAS number is and its SMILES structure is.

It is produced by acetylation of ethylenediamine.

TAED is an important component of detergents and bleaches. Its role is to act as a bleaching activator for active oxygen sources, allowing formulas containing hydrogen peroxide releasing chemicals (specifically the sodium perborate, sodium percarbonate, sodium perphosphate, sodium persulphate, urea peroxide, etc.) to function efficiently in low temperatures (down to 40 °C), leading to substantial energy savings.
