Description
Zinc granule, min. 99.99 %, is a high-purity elemental zinc reagent supplied as granules for laboratory synthesis and analytical work. Graded p.a., the material has particle sizes of 5–15 mm, CAS number 7440-66-6, empirical formula Zn, molar mass 65,37 g/mol and density 7,14 g/cm³. The European inventory identifier is EG nr. 231-175-3. The 5–15 mm particle range supports controlled handling and addition in reaction setups. This zinc quality from manufacturer Carl ROTH is positioned for organic and inorganic synthesis, method development and teaching experiments that call for reliable elemental zinc. Categories such as synthesis reagents and reducing agents reflect typical laboratory use where a minimum assay of 99.99 % underpins reproducible results. The free-flowing granular form suits weighing and portioning at the bench. Laboratories select this grade when consistent metal purity and manageable particle size are required for preparative or analytical workflows.
