Description
Calcium carbonate, min. 98.5 %, is a precipitated inorganic salt supplied in pharmacopoeia quality to Ph.Eur., USP and BP specifications. With CAS number 471-34-1 and empirical formula CaCO₃, it has a molar mass of 100,09 g/mol and a density of 2,93 g/cm³. This fine-grade carbonate is widely used in analytical chemistry, pharmaceutical formulation work, buffer and reagent preparation, and as a controlled calcium source in laboratory and process applications. Produced by manufacturer Carl ROTH, the grade is selected for consistent assay and suitability where pharmacopoeia-compliant inorganic salts are required. Its precipitated form aids handling and dissolution behaviour in aqueous systems. Laboratories working under quality systems appreciate the clear identity data (EG nr. 207-439-9) and the defined minimum assay of 98.5 %, which facilitate documentation and method transfer across research, QC and development environments.

Questions about Calcium carbonate, min. 98.5 %, Ph.Eur., USP, BP, precipitatedated, 500 g
What is this article?
Calcium carbonate, min. 98.5 %, Ph.Eur., USP, BP, precipitatedated, 500 g 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.
