Emodinanthrone is a defined biochemical reference compound supplied for laboratory research and analytical work. It is identified by CAS number 491-60-1 and the empirical formula C₁₅H₁₂O₄, with a molar mass of 256,25 g/mol. These core identifiers support unambiguous substance tracking in method development, comparative studies, and documentation workflows. As a member of the biochemicals range, emodinanthrone fits catalogues focused on organic and bioactive structures used in chemical and life-science laboratories. The material is offered from manufacturer Carl ROTH as part of an expanded biochemical selection intended for research environments that require clear CAS linkage and consistent pack presentation. Laboratories can integrate the compound into internal reference libraries, structure–activity explorations, or supporting analytical sequences without ambiguity over identity or formula. The combination of stated molar mass, empirical formula, and milligram-scale packaging makes the item practical for inventory planning and repeat ordering in both academic and industrial settings. Use remains restricted to professional laboratory handling in line with standard chemical hygiene practice.
