Description
Polymaleic acid is supplied as a 48 % solution in water for laboratory chemical applications requiring a polycarboxylic acid polymer. It is identified by CAS number 26099-09-2 and the repeating empirical formula (C₄H₄O₄)ₙ. Manufacturer data give a density of 1,23 g/cm³ and a flash point of 100 °C, together with UN number 3265 for transport classification. The product is Clear concentration, density and identity parameters help laboratories calculate dilutions, document reagents and align handling with internal safety procedures. This material is offered from manufacturer Carl ROTH within the chemicals assortment for research and process-support use. The aqueous presentation simplifies dosing compared with solid anhydrides or monomers, while keeps quantities manageable for bench-scale experiments. Standard precautions for corrosive organic acid solutions apply during dispensing and storage; consult the linked safety data sheet before first use.

Questions about Polymaleic acid, 48 % in water, 25 g
What is this article?
Polymaleic acid, 48 % in water, 25 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.
