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.
This article belongs on Organic building blocks & synthesis reagents, in Organic chemicals & synthesis reagents.

Questions about Zinc granule, min. 99.99 %, p.a., particle sice, 5-15 mm, 250 g, plastic
What is this article?
Zinc granule, min. 99.99 %, p.a., particle sice, 5-15 mm, 250 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Organic building blocks & synthesis reagents, inside Organic chemicals & synthesis reagents, in Lab chemicals.
A building block is an organic molecule bought to become part of a larger one. The structure, the CAS number and the purity decide it. A 95 percent reagent and a 99.9 percent reagent of the same name leave different impurities in the product. The functional groups are the reason it was chosen.
An organic chemical is built on carbon. In this category it is a building block or a reagent for making another molecule: a starting material, a coupling agent, a polymer, a PEG. Purity is a specification of which impurities remain. The structure, the CAS number and the grade decide whether two bottles are the same substance. Structures and properties are on PubChem. Nomenclature is IUPAC. Classification follows ECHA and the CLP Regulation.
