Description
Poly(p-styrenesulfonic acid) is supplied as a 30 % solution in water for laboratory and process-oriented chemical work, with CAS number 28210-41-5 and empirical formula C₈H₈O₃S. The material is characterised by a molar mass of 184,21 g/mol and a density of 1,11 g/cm³, giving clear physical reference points for formulation and dosing. It supports work in ion-exchange concepts, surface modification trials, dispersion studies and other aqueous polymer chemistry where a defined sulfonic acid functionality is needed. Handling benefits from the stated concentration and density data when preparing dilutions or incorporating the polymer into experimental matrices. Available from manufacturer Carl ROTH, the product carries UN number 2586 and fits chemical and biochemical laboratory inventories that document polymer reagents carefully. balances bench-scale convenience with sufficient quantity for repeated trials. Researchers and technicians can rely on the listed CAS, formula and physical constants for specification sheets, safety assessment inputs and reproducible preparation of working solutions in controlled laboratory environments.

Questions about Poly(p-styrenesulfonic acid), 30 % in water, 100 g
What is this article?
Poly(p-styrenesulfonic acid), 30 % in water, 100 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.
