Description
tri-Sodium phosphate is an anhydrous pure inorganic salt with a minimum assay of 97 %, CAS number 7601-54-9 and empirical formula Na₃PO₄. The compound has a molar mass of 163,94 g/mol and a density of 2,54 g/cm³, This anhydrous tri-sodium phosphate from manufacturer Carl ROTH serves as a defined phosphate source for inorganic synthesis, buffer-related preparations and general analytical or process chemistry where controlled sodium phosphate content is important. The stated purity and anhydrous form support reproducible weighing and dissolution when preparing solutions or solid mixtures. European chemical inventory identification is given by EG number 231-509-8. Documented molar mass and density values assist stoichiometric planning and material characterisation. Suitable for research, teaching and routine laboratory workflows, provides a practical quantity for repeated use without excess bulk. Clear specification of grade and physical data makes this material a reliable option whenever anhydrous tri-sodium phosphate of known composition is required on the bench.

Questions about tri-Sodium phosphate, min. 97 %, pure, anhydrous, 100 g, plastic
What is this article?
tri-Sodium phosphate, min. 97 %, pure, anhydrous, 100 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.
Which category should I open next?
The category is Inorganic chemicals. The sub-category is Inorganic salts. The catalogue is Lab chemicals.
