Description
Colistin sodium methanesulfonate is a polymyxin-derived biochemical reagent provided as the sodium methanesulfonate salt for laboratory research. It carries CAS number 8068-28-8 and the empirical formula C₅₈H₁₁₅N₁₆Na₅O₂₈S₅, with a molar mass of 1759,9 g/mol. This defined salt form is used in microbiological and pharmaceutical studies that require a characterised colistin derivative for experimental work. The product is Identity and molar-mass data follow the manufacturer description from Carl ROTH, supporting reproducible weighing and solution preparation. Colistin sodium methanesulfonate is applied in antimicrobial research, susceptibility testing workflows and related life-science applications where a polymyxin methanesulfonate salt is specified. Documented CAS, formula and pack information help laboratories maintain clear records, transfer methods between sites and manage inventory of specialised biochemical reagents used in bacterial and pharmaceutical research programmes.

Questions about Colistin sodium methanesulfonate, 500 mg
What is this article?
Colistin sodium methanesulfonate, 500 mg 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.
