Description
Clarithromycin, min. 95 %, EP Impurity A is a defined impurity reference material for analytical and pharmaceutical research. It carries CAS number 124412-58-4, the empirical formula C₃₈H₆₉NO₁₄, and a molar mass of 763,95 g/mol. With a stated minimum purity of 95 %, this EP Impurity A grade supports method development, impurity profiling, and chromatographic system suitability work related to macrolide antibiotics. size is practical for calibration, spike-recovery experiments, and limited-quantity reference use in quality-control and R&D laboratories. Analysts can rely on the clear chemical identity data when preparing standards and documenting results. The material is supplied from manufacturer Carl ROTH within the impurities and biochemicals offering and is intended for professional laboratory applications. Consistent labelling of CAS, formula, and purity grade simplifies inventory management and regulatory documentation in impurity-related studies.
This article is part of Chromatography standards (GC, HPLC, pesticides), in Analytical standards & reference materials.

Questions about Clarithromycin, min. 95 %, EP Impurity A, 500 µg
What is this article?
Clarithromycin, min. 95 %, EP Impurity A, 500 µg is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Chromatography standards (GC, HPLC, pesticides), inside Analytical standards & reference materials, in Lab chemicals.
A chromatography standard is the substance, or the mix, injected so a peak can be named and quantified. Pesticide mixes, residual-solvent mixes and single-compound standards are different articles. The concentration and the solvent are the specification. The solvent has to be one the method may contain.
A reference material is the article against which another result is compared. Its value is stated, and the uncertainty of that value is part of the product. An ICP or ion standard is a solution of known concentration. A volumetric standard is for titration. A chromatography standard is the peak you match. The grade names, including pharmacopoeia and ASTM, say which impurities were limited. Identity is checked on PubChem. Names follow IUPAC. Medicinal grades follow the European Pharmacopoeia and USP.
