Description
Ammonium tetraborate tetrahydrate ROTI®METIC 99,999 % (5N) is a high-purity boron salt with CAS number 12228-87-4 and empirical formula (NH₄)₂B₄O₇ · 4 H₂O. It has a molar mass of 263,38 g/mol and a density of 2,367 g/cm³, providing well-defined physical reference values for laboratory preparation and calculation. The product is supplied in a 25 g plastic pack suitable for analytical, synthetic and materials-oriented work. This ultra-high-purity ROTI®METIC grade from manufacturer Carl ROTH supports applications where minimal metallic contamination is critical, including borate chemistry, buffer and flux studies, and specialised inorganic research. The tetrahydrate form is a practical source of ammonium and tetraborate ions for controlled reactions and sample preparation. Clear identification via CAS number and empirical formula simplifies documentation, method transfer and inventory control. Laboratories use ammonium tetraborate tetrahydrate in research workflows that demand reproducible purity, consistent stoichiometry and reliable physical data across successive experimental batches.

Questions about Ammonium tetraborate tetrahydrate, ROTI®METIC 99,999 % (5N), 25 g, plastic
What is this article?
Ammonium tetraborate tetrahydrate, ROTI®METIC 99,999 % (5N), 25 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.
