2-티오바르비투르 산 C화학적 특성, 용도, 생산
화학적 성질
Off-White to Yellow Powder. soluble in hot water, alcohol, ether, alkali and sodium carbonate solution, slightly soluble in water.용도
2-Thiobarbituric acid has been used to measure malondialdehyde (MDA) in lipid peroxidation assay.정의
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.제조 방법
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.일반 설명
2-Thiobarbituric acid is a molecule made up of heteroatoms: nitrogen, sulphur and oxygen.Purification Methods
Crystallise it from water. [Beilstein 24 H 476, 24 I 414, 24 II 275, 24 III/IV 1884.]2-티오바르비투르 산 준비 용품 및 원자재
