Description
di-Sodium tetraborate anhydrous is an inorganic boron salt offered at a minimum purity of 99 % in extra pure grade for laboratory applications. It has the empirical formula Na₂B₄O₇, a molar mass of 201,22 g/mol, a density of 2,354 g/cm³ and a boiling point of 1575 °C. The substance is registered under CAS number 1330-43-4 and EG number 215-540-4. The extra pure specification from manufacturer Carl ROTH supports consistent results in research and quality-control environments. Density and high boiling point data assist process design and safe thermal handling, while the stated assay enables accurate concentration calculations for standard solutions or reaction mixtures. The anhydrous form simplifies stoichiometry compared with hydrated borates when preparing media or reagents. Review the safety data sheet before laboratory use and follow institutional guidelines for inorganic salts.

Questions about di-Sodium tetraborate anhydrous, min. 99 %, extra pure, 250 g, plastic
What is this article?
di-Sodium tetraborate anhydrous, min. 99 %, 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.
