Description
PCB 125 is an individual polychlorinated biphenyl congener offered as a ROTI®Star analytical reference for chromatography and environmental testing. It is characterised by CAS number 74472-39-2, empirical formula C₁₂H₅Cl₅ and a molar mass of 326,43 g/mol, enabling reliable assignment in GC-based congener analysis. Supplied as 5 mg in glass, the pack size suits preparation of stock and intermediate standards without excess material. This PCB 125 grade from manufacturer Carl ROTH is intended for gas chromatography applications, including calibration, retention-time verification and method validation in environmental laboratories. Analysts working on soil, water, biota or industrial samples can incorporate the congener into multi-component PCB mixtures or use it as a discrete marker. The ROTI®Star line addresses the need for well-documented single-congener solids in residue and pollution monitoring. Clear identity data and a practical glass presentation support routine QC, proficiency testing and research workflows focused on pentachlorobiphenyl speciation.

Questions about PCB 125, ROTI®Star, 5 mg, glass
What is this article?
PCB 125, 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.
