Application

Lauroyl peroxide can be used as:
  • A long chain branching(LCB) introducer in polypropylene to improve its mechanical recycling process.
  • A mild oxidant and efficient hydrogen abstractor in the preparation of disulfide compounds through dimerization of corresponding dithiocarbamates.
  • An initiator in the preparation of ion-imprinted polymers(IIPs).
  • An initiator and oxidant to construct erythrina ring system via oxidative radical cyclizations of enamide in the presence of nBu3SnH.

Photosensitized hemolysis of human erythrocytes by hematoporphyrin was suppressed by flavonols such as quercetin and rutin at submillimolar concentrations. The suppression of photohemolysis was accompanied by inhibition of lipid peroxidation by the reagents. Quercetin and rutin were photooxidized in the

A series of (2-alkylthiothiazolin-5-yl)methyl dodecanoates was synthesized from various alkyl N-allylcarbamodithioates and dilauroyl peroxide via a tandem radical hydrogen-abstraction-cyclization-substitution/combination reaction with a 5-exo-trig radical cyclization as a key step. The current route is the first, convenient, and efficient synthesis of
