Description
Polygalacturonic acid is a polymeric uronic acid reagent supplied at a minimum purity of 85 %, with the repeating unit empirical formula (C₆H₈O₆)ₙ and CAS number 25990-10-7. Its approximate molar mass of ~25000 g/mol reflects the polymeric nature of this galacturonic-acid-based material, which is widely used in biochemical, food-chemistry, and plant-cell-wall research contexts. The product is EG number 205-676-2 identifies the substance under European chemical inventory practice. Sourced from manufacturer Carl ROTH, this grade supports synthesis and analytical workflows where a defined polygalacturonic backbone is required without unnecessary formulation additives. Handle according to standard laboratory chemical hygiene; consult the accompanying safety documentation for detailed hazard and handling guidance before use in research or process development.
This article is part of Acids, in Acids & bases.

Questions about Polygalacturonic acid, min. 85 %, 25 g, plastic
What is this article?
Polygalacturonic acid, min. 85 %, 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.
