Description
Zinc chloride is an analytical-grade inorganic salt supplied at a minimum purity of 97 % (p.a.). It is characterised by CAS number 7646-85-7 and EG number 231-592-0, the empirical formula ZnCl₂, a molar mass of 136,28 g/mol, a density of 2,91 g/cm³ and a boiling point of 732 °C. This anhydrous chloride is used in laboratory synthesis, catalyst and reagent preparation, and analytical workflows that call for a defined zinc source of p.a. quality. The product is Stated physical constants support stoichiometric calculations, concentration planning and method documentation. Typical application areas include inorganic and organic synthesis steps involving zinc salts, preparation of specialised reagents, and teaching or quality-control tasks where a clear assay grade is preferred. The combination of purity statement, formula and measured properties enables informed selection against protocol requirements without additional unsupported claims.
This article belongs on Inorganic salts, in Inorganic chemicals.

Questions about Zinc chloride, min. 97 %, p.a., 500 g, plastic
What is this article?
Zinc chloride, min. 97 %, p.a., 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 Produits chimiques de laboratoire et industriels.
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.
