Charcoal, p.a., 250 g, plastic

Charcoal is a p.a. grade carbon material intended for laboratory filtration, decolourisation and adsorption applications. Identified by CAS number 7440-44-0 and empirical formula C, it has a molar mass of 12,01 g/mol and is supplied as a practical for everyday bench use. In analytical and preparative chemistry, charcoal is widely employed to remove coloured impurities from organic solutions, to polish reaction mixtures and to support sample clean-up before spectroscopic or chromatographic measurement. This reagent from manufacturer Carl ROTH fits workflows that specify analytical-grade carbon rather than technical charcoal. Typical uses include treatment of crystallisation liquors, clarification of extracts and teaching experiments that demonstrate surface adsorption. The EG number 231-153-3 provides a clear regulatory identity for documentation and inventory systems. Laboratories working across organic synthesis, natural-product isolation and general wet chemistry can rely on this p.a. charcoal when a defined elemental carbon source is required without additional functional claims beyond the stated analytical grade.
