Description
Calcium chloride dihydrate is an analytical-grade inorganic salt with a minimum purity of 99 %, meeting p.a. and ACS requirements. It carries CAS number 10035-04-8, EG nr. 600-075-5 and the empirical formula CaCl₂ · 2 H₂O. The molar mass is 147,02 g/mol and the density is 1,85 g/cm³. This hydrated calcium salt is widely used to prepare calcium-containing solutions, drying and desiccant systems, buffer and media components, and general inorganic synthesis in research and quality-control laboratories. The product is Specification data from manufacturer Carl ROTH align with p.a./ACS expectations, supporting applications that demand well-defined purity and identity. Clear labelling of CAS, formula and grade simplifies documentation, purchasing and inventory management. Calcium chloride dihydrate remains a standard laboratory reagent whenever a reliable source of soluble calcium and chloride ions is required under controlled analytical conditions, from classical wet chemistry to modern instrumental sample preparation.

Questions about Calcium chloride dihydrate, min. 99 %, p.a., ACS, 10 g, glass
What is this article?
Calcium chloride dihydrate, min. 99 %, p.a., ACS, 10 g, glass 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.
