Description
Maleic anhydride is an organic reagent supplied at min. 99,5 % purity for synthesis, with CAS number 108-31-6 and empirical formula C₄H₂O₃. The molar mass is 98,06 g/mol, density 1,48 g/cm³, flash point 103 °C and boiling point 200,1 °C, giving clear physical reference data for planning synthetic work. This grade is Key identifiers further include EG nr. 203-571-6 and UN number 2215 as stated by the manufacturer. Maleic anhydride from manufacturer Carl ROTH is positioned for chemical synthesis workflows in research and development laboratories handling cyclic anhydrides. The combination of stated purity, molar mass and density supports stoichiometric calculations, solvent selection and process documentation. Use this material where a synthesis-grade maleic anhydride with transparent analytical identifiers is required for organic transformations, intermediate preparation or method development under controlled laboratory conditions.

Questions about Maleic anhydride, min. 99,5 %, for synthesis, 250 g, glass
What is this article?
Maleic anhydride, min. 99,5 %, for synthesis, 250 g, glass 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.
