Iron(II) ethylenediammonium sulfate tetrahydrate, ROTI®Star CRM for volumetry, 80 g

Iron(II) ethylenediammonium sulfate tetrahydrate is a ROTI®Star CRM for volumetry with CAS number 34962-29-3, empirical formula FeC₂H₁₀N₂S₂O₈ · 4 H₂O and a molar mass of 382,15 g/mol. Assigned EC number 264-357-6, this tetrahydrate presents iron(II) together with ethylenediammonium and sulfate in a defined solid form for volumetric analysis. The article is packed as 80 g, a practical unit quantity for laboratory CRM use in volumetry. Analytical groups specify iron(II) ethylenediammonium sulfate tetrahydrate when a method calls for this CAS identity and molar mass rather than a generic iron(II) salt. The ROTI®Star CRM for volumetry grade comes from manufacturer Carl ROTH for quantitative volumetric procedures. Four water molecules of hydration are included in the empirical formula, so solution preparation should use 382,15 g/mol as the molar mass of the tetrahydrate. The chemical belongs to the laboratory chemicals range and is identified consistently by name, CAS number, EC number and formula. The 80 g pack is the listed unit quantity of this CRM for volumetry.
