Description
PCB 2 is a monochlorobiphenyl reference material from the ROTI®Star portfolio, provided as a neat solid for analytical chemistry. It carries CAS number 2051-61-8 and empirical formula C₁₂H₉Cl, with a molar mass of 188,65 g/mol. Individual PCB congeners are essential in environmental analysis and gas chromatography, where they enable retention matching, response-factor determination and quantitative assessment of chlorinated biphenyl residues. This offering from manufacturer Carl ROTH supports reproducible standard preparation for GC workflows and related environmental monitoring programmes. Clear identity parameters help laboratories maintain traceable calibration series and verify separation performance. Suitable for research and routine analytical settings that require a defined monochloro biphenyl reference, PCB 2 integrates into validated chromatographic methods under customary laboratory safety practice for chlorinated aromatics.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about PCB 2, ROTI®Star, 10 mg, glass
What is this article?
PCB 2, 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.
