Description
PCB 56 is an individual polychlorinated biphenyl congener supplied as ROTI®Star reference material for laboratory analysis. Characterised by CAS number 41464-43-1, empirical formula C₁₂H₆Cl₄ and a molar mass of 291,99 g/mol, it provides a well-defined tetrachlorobiphenyl identity for calibration, identification and quantitative work. The congener is relevant to environmental analysis and gas chromatography, where single PCB structures are needed to build calibration curves, verify separation performance or support confirmatory measurements in residue studies. Packaged as 5 mg in glass, the material is convenient for preparing stock solutions, dilutions and spiked matrices used in method development and routine quality control. Laboratories monitoring persistent organic pollutants can incorporate PCB 56 into multi-congener panels to map retention and detector response under GC conditions. This ROTI®Star item from manufacturer Carl ROTH fits established workflows in environmental and chromatographic laboratories that rely on discrete congener standards. Clear CAS, EG and formula data support documentation and traceability in analytical records. PCB 56 is intended for professional laboratory use wherever a defined tetrachlorobiphenyl reference is required for gas-chromatographic environmental applications.

Questions about PCB 56, ROTI®Star, 5 mg, glass
What is this article?
PCB 56, ROTI®Star, 5 mg, glass is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Chromatography standards (GC, HPLC, pesticides), inside Analytical standards & reference materials, in Lab chemicals.
A chromatography standard is the substance, or the mix, injected so a peak can be named and quantified. Pesticide mixes, residual-solvent mixes and single-compound standards are different articles. The concentration and the solvent are the specification. The solvent has to be one the method may contain.
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.
