This product is tested for solubility in ethanol at 50mg/ml. The ethanol stock solution may then be diluted out in water or aqueous buffers. Various sources state that TEMPO may be dissolved directly in water at 9mg/ml. This information has not been validated.

General description
For a synthetic protocol using NMP initiators, contributed by Prof. Karen Wooley, please visit our technology spotlight.
Application
Stable nitroxide radical useful in controlling living polymerizations
TEMPO (2,2,6,6-Tetramethyl-1-piperidinyloxy) was used for trapping the styrenyl radical generated from benzoyl peroxide during nitroxide-mediated radical polymerization of styrene.[1] TEMPO-mediated oxidation was employed for the carboxylation of water-resistant nanofibrillated cellulose (NFC) films.[2]

Homogeneous Cu/TEMPO catalyst systems (TEMPO = 2,2,6,6-tetramethylpiperidine-N-oxyl) have emerged as some of the most versatile and practical catalysts for aerobic alcohol oxidation. Recently, we disclosed a (bpy)Cu(I)/TEMPO/NMI catalyst system (NMI = N-methylimidazole) that exhibits fast rates and high selectivities, even
