Description
PCB 189 is a heptachlorobiphenyl reference material from the ROTI®Star line, offered as a neat solid for high-level analytical use. Identified by CAS number 39635-31-9 and empirical formula C₁₂H₃Cl₇, it has a molar mass of 395,32 g/mol and the EG number 690-157-7. The congener is supplied as a 5 mg portion in glass, suited to environmental analysis and gas chromatography where defined PCB standards support calibration, method validation and congener-specific quantification. Laboratories monitoring persistent organic pollutants in environmental, food or industrial matrices can incorporate this material into GC workflows that demand clear chemical identity and reproducible response. Available from manufacturer Carl ROTH as part of the ROTI®Star portfolio, PCB 189 fits routine and research applications that rely on individual PCB congeners rather than technical mixtures. Its compact glass pack supports economical use in standard preparation and quality-control schemes while maintaining traceability to the stated CAS and formula data.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about PCB 189, ROTI®Star, 5 mg, glass
What is this article?
PCB 189, 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.
