4-Hydroxy TEMPO or TEMPOL,is a heterocyclic compound. It is used as a catalyst and chemical oxidant by virtue of being a stable aminoxyl radical.
4-Hydroxy TEMPO is produced from triacetone amine, which is itself made via the condensation of acetone and ammonia.

Use
4-Hydroxy TEMPO is free radical inhibitor.It has good inhibition effect in aerobic and anaerobic environment.
4-Hydroxy TEMPO prevents the self-polymerization of olefin monomers during production, separation, refining, storage or transportation.
And it controls and adjusts the degree of polymerization of olefins and their derivatives in organic synthesis reactions.
It has inhibition effect for acrylates, methacrylates, acrylic acid, acrylonitrile, styrene, butadiene.
