Description
D-Isoascorbic acid is a crystalline organic acid with the empirical formula C₆H₈O₆ and CAS number 89-65-6, supplied at a minimum purity of 98 %. It has a molar mass of 176,13 g/mol and a density of 1,707 g/cm³, providing a well-documented specification for laboratory use. Packed as 25 g in plastic, this stereoisomer of ascorbic acid is suited to formulation trials, analytical reference work and synthetic or biochemical studies that call for erythorbic acid chemistry. The crystalline solid handles conveniently for weighing and solution preparation in research and quality-control settings. This material from manufacturer Carl ROTH is listed under EG number 201-928-0 and fits catalogue supply for chemistry, life-science and food-related laboratory applications where D-isoascorbic acid is specified. Clear molar mass and density data support identity checks and documentation. The 25 g pack size balances economy with practical bench use for method development and small-batch experiments. Store and handle according to good laboratory practice and consult the safety data sheet before first use.
This article is part of Acids, in Acids & bases.

Questions about D-Isoascorbic acid, min. 98J %, cryst., 25 g, plastic
What is this article?
D-Isoascorbic acid, min. 98J %, cryst., 25 g, plastic 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.
