Description
PCB 3 is a monochlorobiphenyl reference material in the ROTI®Star range, offered as a neat solid for analytical laboratory use. Identified by CAS number 2051-62-9 and empirical formula C₁₂H₉Cl, it has a molar mass of 188,65 g/mol and a boiling point of 282 °C. The product is supplied in a 50 mg glass pack suitable for preparing calibration solutions and working standards. Defined PCB congeners are widely applied in environmental analysis and chromatography, particularly gas chromatography, where they support method development, retention-time assignment and quantitative residue work. This grade from manufacturer Carl ROTH fits laboratories that require a clearly specified monochloro biphenyl for GC-based monitoring of environmental matrices and related quality-control tasks. Consistent identity data help establish response factors and verify instrument performance across sequences. Use under standard laboratory controls for chlorinated aromatic compounds and integrate into validated analytical workflows for environmental and chromatographic applications.

Questions about PCB 3, ROTI®Star, 50 mg, glass
What is this article?
PCB 3, ROTI®Star, 50 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.
