Stable Radicals [Synthetic Reagents] — compiles stable free radical compounds of the piperidine-N-oxyl (TEMPO) class and their derivatives substituted with functional groups such as amino, acetamido, or alkyne. The structural stability of these radicals makes them unique reagents for various oxidation transformations and radical mechanism research.
Stable Radicals [Synthetic Reagents] are used by synthetic chemists as catalysts for the selective oxidation of primary and secondary alcohols to aldehydes or ketones via TEMPO-mediated oxidation. Substituted derivatives also function as spin labels in EPR spectroscopy and as control agents in nitroxide-mediated radical polymerization in polymer materials research.

Pay attention to the purity grade, for example sublimation-purified products for high-precision applications, as well as the functional substituents required, such as alkyne or amino groups for further conjugation. All products are genuine Tokyo Chemical Industry (TCI) Japan products, with purity, packaging, and storage conditions listed on the page of each item.
