Description
L-Dehydroascorbic acid is a biochemical reagent supplied at a minimum purity of 95 % for laboratory research applications. Identified by CAS number 490-83-5 and empirical formula C₆H₆O₆, it has a molar mass of 174,11 g/mol. The product is This grade from manufacturer Carl ROTH supports experiments in redox chemistry, vitamin C metabolism pathways, and related assay development where a defined L-dehydroascorbic acid standard is required. Clear specification of purity and molecular data facilitates reproducible weighing and solution preparation. Store at −20 °C under appropriate laboratory conditions to maintain integrity. The one-gram unit balances economy with practical bench use for method set-up, calibration, and small-series experiments in chemical and life-science environments focused on ascorbic acid derivatives.

Questions about L-Dehydroascorbic acid, min. 95 %, 1 g
What is this article?
L-Dehydroascorbic acid, min. 95 %, 1 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.
