Description
Sodium hydrogen carbonate is an inorganic salt of min. 99 % purity in Ph.Eur., extra pure quality, The empirical formula is NaHCO₃, with CAS number 144-55-8 and EG number 205-633-8. It has a molar mass of 84,01 g/mol and a density of 2,21 g/cm³. This grade is appropriate for buffer preparation, pH adjustment, analytical work, and other applications that call for pharmacopoeia-quality sodium hydrogen carbonate. Sodium hydrogen carbonate from manufacturer Carl ROTH provides a clearly specified extra-pure Ph.Eur. option for laboratories that require consistent inorganic salt quality without unnecessary packaging bulk.
This article is part of Inorganic salts, in Inorganic chemicals.

Questions about Sodium hydrogen carbonate, min. 99 %, Ph.Eur., extra pure, 1 kg, plastic
What is this article?
Sodium hydrogen carbonate, min. 99 %, Ph.Eur., extra pure, 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.
