Description
PCB 72 is a polychlorinated biphenyl reference congener from the ROTI®Star range, intended for precise analytical use in environmental and chromatographic laboratories. It carries CAS number 41464-42-0, empirical formula C₁₂H₆Cl₄, and a molar mass of 291,99 g/mol, placing it among the tetrachlorobiphenyl standards employed in residue analysis. Supplied as a 10 mg quantity in glass, the material is suitable for preparing calibration solutions, system suitability checks, and confirmatory standards for gas chromatography. Laboratories performing environmental monitoring and PCB congener profiling use discrete standards such as PCB 72 to support reliable identification and quantification. Available from manufacturer Carl ROTH, this reference solid integrates into GC workflows focused on environmental contaminants and method validation. Applications span gas-chromatographic screening, calibration curve construction, and quality-control programmes that require well-defined individual PCB congeners. The glass presentation supports orderly storage and handling of small analytical portions in the laboratory.

Questions about PCB 72, ROTI®Star, 10 mg, glass
What is this article?
PCB 72, 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.
