Description
Sodium acetate trihydrate, min. 99 %, p.a., ACS, ISO is a high-purity analytical salt with CAS number 6131-90-4 and EG number 204-823-8. The empirical formula NaCH₃COO · 3 H₂O corresponds to a molar mass of 136,08 g/mol. Density is reported as 1,42 g/cm³, and the flash point exceeds 250 °C, supporting safe handling under standard laboratory conditions. Meeting p.a., ACS, and ISO expectations, this grade is intended for quantitative analysis, buffer preparation, and other work where tight assay control matters. The material is Sodium acetate trihydrate dissolves readily in water and is widely applied in biochemistry, chromatography, and inorganic analysis as a mild base or buffering component. From manufacturer Carl ROTH, this ACS/ISO-compliant salt offers a consistent source for laboratories that require documented purity without compromising routine throughput. Its defined hydrate form helps maintain stoichiometric accuracy when preparing standard solutions and reaction mixtures across analytical and research settings.

Questions about Sodium acetate trihydrate, min. 99 %, p.a., ACS, ISO, 500 g, plastic
What is this article?
Sodium acetate trihydrate, min. 99 %, p.a., ACS, ISO, 500 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.
