Aplicação

1,3-Diethyl-2-thiobarbituric acid (DETBA) was used as coinitiator during the photopolymerization of dental materials. It was used as reagent in electrochemical oxidation of 3,4-dihydroxybenzoic acid to yield benzofuro[2,3-d]pyrimidine derivatives. It was used in DETBA assay for determination of nicotine metabolites in human urine by HPLC.

We investigated the influence of different concentrations of Fe3+, phosphoric acid, butylated hydroxytoluene and glutathione on the production of the malondialdehyde-1,3-diethyl-2-thiobarbituric acid adduct in plasma lipid extracts. Following organic solvent extraction the stable product was analyzed by spectrophotometry (537 nm)

The ethyl-4-dimethylaminobenzoate (EDAB) is widely used as a coinitiator of the camphorquinone (CQ), but in acidic circumstances it might present some instability, reducing the polymerization efficiency of the material. Considering this, new coinitiators are being evaluated. Hence, this study evaluated

Electrochemical oxidation of 3,4-dihydroxybenzoic acid (1) in the presence of 1,3-dimethylbarbituric acid (2) and 1,3-diethyl-2-thiobarbituric acid (3) as nucleophiles in aqueous solution has been studied using cyclic voltammetry and controlled-potential coulometry. The results indicate that 1 via Michael reaction under
