Description
Ammonium hexafluorosilicate is an extra pure inorganic compound with a minimum assay of 98,5 %, intended for laboratory synthesis, materials work and specialised fluoride chemistry. It is registered under CAS number 16919-19-0 and EG nr. 240-968-3, with the empirical formula (NH₄)₂SiF₆, a molar mass of 178,14 g/mol and a density of 2,011 g/cm³. These well-defined physical and chemical parameters support accurate weighing, solution preparation and documentation in research or quality-control settings. The product is Available from manufacturer Carl ROTH in extra pure quality, this salt suits applications that call for a consistent ammonium hexafluorosilicate source without additional purity claims beyond the stated minimum. Laboratories can integrate the material into inorganic preparations, surface-related studies and general reagent inventories where clear CAS, formula and density data are required for method transfer and safety assessment.
This article is part of Inorganic salts, in Inorganic chemicals.

Questions about Ammonium hexafluorosilicate, min. 98,5 %, extra pure, 250 g, plastic
What is this article?
Ammonium hexafluorosilicate, min. 98,5 %, extra pure, 250 g, plastic is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Inorganic salts, inside Inorganic chemicals, in Lab chemicals.
An inorganic salt is an ionic solid, a chloride, a sulfate, a nitrate, a phosphate. The degree of hydration changes the mass that contains one mole of the ion. Analytical grade limits the foreign ions. A hydrate and the anhydrous salt are not interchangeable by weight.
An inorganic chemical is a salt, an acid or base in solid form, a metal, an oxide, or an element. The waters of hydration are part of the formula: a hydrate and an anhydrous salt are different masses for the same ion. Trace metals matter when the salt will be used in analysis. Nanomaterials add particle size to the specification. Look the substance up on PubChem. Hazard classes are on ECHA, under the CLP Regulation and REACH. Transport of the dangerous ones is explained by the UNECE.
