Description
Sodium acetate trihydrate is an inorganic salt supplied at a minimum purity of 99 % in Ph.Eur. quality for laboratory and pharmacopoeia-oriented applications. It carries CAS number 6131-90-4 and EG number 204-823-8, with the empirical formula NaCH₃COO · 3 H₂O, a molar mass of 136,08 g/mol and a density of 1,42 g/cm³. The flash point is above 250 °C. This crystalline hydrate is commonly employed in buffer preparation, pH adjustment, precipitation protocols and other aqueous chemistry workflows where a defined acetate source is required. Its Ph.Eur. specification supports use in environments that follow pharmacopoeial standards for inorganic salts. Chemistry and life-science laboratories can rely on the stated identity, purity and physical data when formulating acetate buffers or performing general inorganic reagent tasks. The kilogram pack size offers efficient handling for frequent or volume-demanding applications without compromising documented quality attributes.

Questions about Sodium acetate trihydrate, min. 99 %, Ph.Eur., 1 kg, plastic
What is this article?
Sodium acetate trihydrate, min. 99 %, Ph.Eur., 1 kg, 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.
Shelves beside this one are Metals, elements & oxides and Nanomaterials & quantum dots.
What should I check before I order?
The technical information on this page is the manufacturer's sheet. Read that, not a rewritten specification.
When this page shows a safety data sheet, use that manufacturer file. Hazard text does not belong in the sales description. For a pack size, a grade or a certificate that is not on the page, send a quote request or contact the team.
