Description
2-Thiobarbituric acid is an organic heterocyclic reagent offered at a minimum purity of 95 % for laboratory and biochemical work. Identified by CAS number 504-17-6 and the empirical formula C₄H₄N₂O₂S, it has a molar mass of 144,15 g/mol. The compound is frequently applied in analytical chemistry, notably in colorimetric assays linked to lipid peroxidation and related oxidative-stress measurements, as well as in broader synthetic and method-development tasks. This grade from manufacturer Carl ROTH is intended for professional users who require a clearly specified thiobarbituric acid for reproducible experimental workflows. Handle according to standard laboratory safety practice and consult the accompanying documentation before use.
This article is part of Acids, in Acids & bases.

Questions about 2-Thiobarbituric acid, min. 95 %, 250 g
What is this article?
2-Thiobarbituric acid, min. 95 %, 250 g is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Acids, inside Acids & bases, in Lab chemicals.
An acid on this shelf is the substance itself, concentrated or as a stated solution: hydrochloric, sulfuric, nitric, acetic and the rest. Concentration, purity and the trace metals decide the use. A concentrated acid and a volumetric solution of the same name are different products, and both burn.
An acid donates a proton. A base accepts one. In the bottle, the practical differences are the concentration, the purity and the anion or cation that comes along. Concentrated mineral acids are a different article from a dilute volumetric solution. The water in the acid, and the trace metals, decide whether it can be used for analysis. Check the substance on PubChem and the classification on ECHA CLP. Transport is the UNECE dangerous-goods framework. The legal texts are the CLP Regulation and REACH.
