Description
Ammonium chloride is a high-purity inorganic salt offered at a minimum assay of 99.5 % and conforming to Ph.Eur., USP and BP pharmacopoeia quality. The compound carries CAS number 12125-02-9, empirical formula NH₄Cl, a molar mass of 53,49 g/mol and a density of 1,53 g/cm³, making it straightforward to dose in buffer systems, electrolyte media and classical wet chemistry. It is Typical uses include pH adjustment, chloride-ion sources and preparation of reference or reagent solutions where multi-pharmacopoeia compliance is required. This salts-in-pharmacopoeia-quality material from manufacturer Carl ROTH supports regulated and research environments that demand documented identity and assay. EG nr. 235-186-4 identifies the substance in the European inventory. Clear specification of purity grades and physical constants helps ensure batch-to-batch consistency for methods that rely on ammonium chloride as a defined inorganic reagent.

Questions about Ammonium chloride, min. 99.5 %, Ph.Eur., USP, BP, 500 g, plastic
What is this article?
Ammonium chloride, min. 99.5 %, Ph.Eur., USP, BP, 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 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.
