Description
Cefotaxime sodium salt is a cephalosporin antibiotic salt supplied at 914–964 µg/mg on a dried basis according to USP, with CAS number 64485-93-4 and empirical formula C₁₆H₁₆N₅NaO₇S₂. The molar mass is 477,40 g/mol, and the EC number is 264-915-9. This solid is intended for laboratory and research chemical use where a defined USP-related potency on the dried basis is required. Cefotaxime sodium salt from manufacturer Carl ROTH is offered as a characterised chemical with stated activity range rather than as a finished medicinal product. The sodium salt form and documented µg/mg dried-basis values assist accurate weighing and potency calculation. Laboratories handling beta-lactam research reagents will recognise the need for clear CAS, formula, and USP potency data. Use this when a compact quantity of cefotaxime sodium salt with the stated 914–964 µg/mg dried-basis specification is needed for controlled experimental work.

Questions about Cefotaxime sodium salt , 914 - 964 µg/mg dreid basis, USP, 1 g, glass
What is this article?
Cefotaxime sodium salt , 914 - 964 µg/mg dreid basis, USP, 1 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.
