Description
Oxalacetic acid is a biochemical reagent offered at a minimum purity of 98 % for biochemistry applications. It is characterised by CAS number 328-42-7 and EG number 206-329-8, the empirical formula C₄H₄O₅, and a molar mass of 132,07 g/mol. A flash point of 174 °C is reported for the solid. The product is As a key four-carbon dicarboxylic intermediate, oxalacetic acid supports work on the citric acid cycle, transamination chemistry, and related pathway investigations in research laboratories. Identity and purity information from manufacturer Carl ROTH enable straightforward incorporation into validated biochemical protocols. The compact helps preserve material integrity between uses while providing sufficient quantity for multiple experimental runs. Laboratories can apply the stated molar mass and formula directly in stoichiometric planning and analytical documentation for reproducible results.

Questions about Oxalacetic acid, min. 98 %, for biochemistry, 5 g, glass
What is this article?
Oxalacetic acid, min. 98 %, for biochemistry, 5 g, glass 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.
