Description
PCB 124 is a single-congener polychlorinated biphenyl reference material in the ROTI®Star range, designed for high-resolution chromatographic analysis. Key identifiers include CAS number 70424-70-3, empirical formula C₁₂H₅Cl₅ and molar mass 326,43 g/mol, which anchor its use in quantitative and qualitative GC methods. The product is supplied as 5 mg in glass, providing a laboratory-scale amount for standard preparation and system suitability checks. PCB 124 from manufacturer Carl ROTH supports environmental analysis and gas chromatography workflows where individual pentachlorobiphenyl congeners must be resolved and confirmed. Typical uses include calibration curves, spike recovery studies and verification of separation performance on capillary columns. Research and routine laboratories monitoring persistent organic pollutants can integrate this solid reference into established PCB panels. The ROTI®Star presentation emphasises analytical clarity and practical handling for chromatography-driven applications rather than bulk chemical supply, helping maintain traceable congener-level results in complex sample matrices.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about PCB 124, ROTI®Star, 5 mg, glass
What is this article?
PCB 124, ROTI®Star, 5 mg, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in ICP, AAS & ion standards, inside Analytical standards & reference materials, in Lab chemicals.
An ICP, AAS or ion standard is a solution of a stated element or ion at a stated concentration, with an uncertainty. It is the calibration point of a spectrometer or an electrode. The matrix, often dilute acid, has to match the method. A standard past its expiry is not that concentration.
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.
