Description
PCB 123 is a defined polychlorinated biphenyl congener supplied as a ROTI®Star reference material for environmental analysis and chromatographic work. It carries CAS number 65510-44-3, the empirical formula C₁₂H₅Cl₅ and a molar mass of 326,43 g/mol, giving laboratories a clear chemical identity for calibration and identification tasks. The compound is packed as 5 mg in glass, a convenient small quantity for preparing stock and working solutions in gas chromatography and related separation methods. Offered by manufacturer Carl ROTH within the ROTI®Star line, this congener supports method development, quality control and confirmatory analysis of PCB residues in environmental matrices. Its well-documented molecular composition and EG number 690-284-8 help analysts maintain traceable records and consistent peak assignment. Suitable for routine GC workflows and specialised environmental monitoring programmes, PCB 123 provides a focused standard when individual congener resolution is required rather than technical mixtures alone.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about PCB 123, ROTI®Star, 5 mg, glass
What is this article?
PCB 123, 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.
