Questions about Clarithromycin, min. 95 %, EP Impurity L, 1 mg
What is this article?
Clarithromycin, min. 95 %, EP Impurity L, 1 mg 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.
