Description
PCB 73 is a defined polychlorinated biphenyl congener offered as a ROTI®Star reference material for analytical and environmental laboratories. Identified by CAS number 74338-23-1 and empirical formula C₁₂H₆Cl₄, it has a molar mass of 291,99 g/mol and belongs to the tetrachlorobiphenyl group used in residue and contaminant work. The product is supplied as a 5 mg portion in glass, suited to preparation of calibration solutions and verification standards for gas chromatography. Individual PCB congeners such as PCB 73 support identification and quantification in environmental analysis, method development, and quality-control sequences where clear chromatographic reference points are required. This material from manufacturer Carl ROTH fits workflows that rely on discrete congener standards rather than complex technical mixtures. Typical applications include GC-based screening and confirmation of polychlorinated biphenyls in environmental matrices. The compact glass pack format is practical for controlled handling of small analytical quantities in chromatography and environmental monitoring laboratories.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about PCB 73, ROTI®Star, 5 mg, glass
What is this article?
PCB 73, 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.
