| 2-Thiobarbituric acid Usage And Synthesis |
| Chemical Properties | Off-White to Yellow Powder. soluble in hot water, alcohol, ether, alkali and sodium carbonate solution, slightly soluble in water. |
| Uses | 4,6-Dihydroxy-2-mercaptopyrimidine can be used to quantitate lipopolysaccharides, carrageenan, and sialic acids, and to detect lipid hydroperoxides and lipid oxidation. |
| Uses | 2-Thiobarbituric acid has been used to measure malondialdehyde (MDA) in lipid peroxidation assay. |
| Preparation | 2-thiobarbituric acid was synthesized by the reaction of diethyl malonate with thiourea. Dissolve thiourea in methanol, add sodium methoxide and diethyl malonate, heat under reflux for 4-5h, then distill under reduced pressure to recover methanol to the end, and add hydrochloric acid to acidify to pH 1-2 after cooling. After standing overnight, thiobarbituric acid crystals were precipitated, filtered, and recrystallized with water to obtain the pure product. |
| Definition | ChEBI: 2-thiobarbituric acid is a barbiturate, the structure of which is that of barbituric acid in which the oxygen at C-2 is replaced by sulfur. It has a role as a reagent and an allergen. |
| General Description | 2-Thiobarbituric acid is a molecule made up of heteroatoms: nitrogen, sulphur and oxygen. |
| Biochem/physiol Actions | 2-Thiobarbituric acid (TBA) is useful to quantitate lipopolysaccharides, carrageenan, and sialic acids. It is also used to detect lipid hydroperoxides and lipid oxidation. It has applications in the field of medicine and biochemistry. TBA may possess the ability to prevent metal corrosion. |
| Purification Methods | Crystallise it from water. [Beilstein 24 H 476, 24 I 414, 24 II 275, 24 III/IV 1884.] |
