Description
PCB 158 is a hexachlorobiphenyl congener offered as a ROTI®Star reference material for analytical and environmental laboratories. Identified by CAS number 74472-42-7 and empirical formula C₁₂H₄Cl₆, it has a molar mass of 360,88 g/mol and is supplied neat in a 10 mg glass pack for accurate weighing and standard preparation. This defined PCB congener is intended for gas chromatography and related chromatographic workflows used in environmental analysis. Typical laboratory uses include preparation of calibration solutions, establishment of retention data and response factors, and support of residue and monitoring methods that target polychlorinated biphenyls. The small glass presentation suits micro-scale work where only milligram quantities are required for stock and working standards. PCB 158 from manufacturer Carl ROTH belongs to the ROTI®Star range assembled for chromatography-focused applications. Analysts in environmental, food-related and industrial monitoring settings can incorporate the material into GC method development, quality-control schemes and congener-specific quantification protocols. Handling should follow standard laboratory practice for chlorinated aromatic reference substances, with attention to the associated transport classification for this compound class.
This article belongs on ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about PCB 158, ROTI®Star, 10 mg, glass
What is this article?
PCB 158, ROTI®Star, 10 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.
