1,3,7-Trimethyluricacid-d9 is intended for use as an internal standard for the quantification of 1,3,7-trimethyluricacid by GC- or LC-MS. 1,3,7-Trimethyluricacid is a derivative of uricacid and a metabolite of caffeine. It is formed from caffeine by the cytochrome P450 isoform CYP3A4. 1,3,7-Trimethyluricacid scavenges hydroxyl radicals in a cell-free assay and inhibits t-butyl hydroperoxide-induced lipid peroxidation by 56.5% in isolated human erythrocyte membranes.
Cyanuricacid is a chlorine stabilizer and a precursor to N-chlorinated cyanurates. It is used to disinfect water and crosslink agents for polyurethane resins.
Lauricacid-13C is intended for use as an internal standard for the quantification of lauricacid by GC- or LC-MS. Lauricacid is a medium-chain saturated fatty acid. It has been found at high levels in coconut oil.1Lauricacid induces the activation of NF-κB and the expression of COX-2, inducible nitric oxide synthase (iNOS), and IL-1α in RAW 264.7 cells when used at a concentration of 25 μM.2
