General description

4,N,N-Trimethylaniline is a N-methyl-N-alkylaniline. Its reaction with vinyl ether catalyzed by CuCl2 has been reported to afford tetrahydroquinolines.[1] Its radical cation undergoes reaction with the anthracene radical anion and generation of electrogenerated chemiluminescence (ECL) has been observed.[2]

Application

  • Charge-transfer complexes for redox polymerization: 4,N,N-Trimethylaniline used for on-demand amine/peroxide redox polymerization. This research offers a new perspective on the use of 4,N,N-Trimethylaniline in creating controlled polymer structures, which is crucial for various industrial and pharmaceutical applications (Garra et al., 2018).

Commercially available acrylic bone cements are two-component systems based on the polymerization of methyl methacrylate around poly(methyl methacrylate) particles. When benzoyl peroxide (BPO), which is the initiator, in the powder component meets accelerator (N,N-dimethyl-p-toluidine (DMpT)) in the liquid component, radicals

Porous-free, two-solution bone cements have been developed in our laboratory as an alternative to commercial powder/liquid formulations. Each pair of solutions consist of poly(methyl methacrylate) (PMMA) powder dissolved in methyl methacrylate (MMA) monomer, with benzoyl peroxide (BPO) added to one

The objective of this investigation was to analyze whether various combinations of the ROS scavengers glutathione (GSH), N-acetyl-cysteine (NAC), and vitamins C and E decrease DNA damage due to visible-light-irradiated (VL-irradiated) camphorquinone/N,N-dimethyl-p-toluidine (CQ/DMT) compared with individual vitamin C or E.

The aim of this study was to examine the apoptotic and necrotic influence of four dental resin polymerization initiators--namely benzoyl peroxide (BPO), camphorquinone (CQ), dimethylaminoethyl methacrylate (DMAEMA), and dimethyl-para-toluidine (DMPT)--on human gingival fibroblast (HGF) cells. To this end, the growth
