Description
PCB 127 is a pentachlorobiphenyl congener for analytical reference applications, identified by CAS number 39635-33-1 and the empirical formula C₁₂H₅Cl₅. This polychlorinated biphenyl has a molar mass of 326,43 g/mol and is offered in the ROTI®Star range for environmental analysis and chromatography. Gas chromatography laboratories depend on individual PCB congeners when establishing calibrations, validating methods and performing quality-control checks in residue monitoring. The material is supplied as a 5 mg quantity in glass from manufacturer Carl ROTH, supporting precise preparation of stock and dilute standards. PCB 127 provides defined congener identity for the detection and quantification of polychlorinated biphenyls in environmental and related sample matrices. Its specified composition aids consistent peak recognition and response assessment in GC-based workflows. Analysts may incorporate the congener into multi-residue standard mixtures, recovery studies and instrument verification routines. Sound laboratory handling practices help maintain the integrity of this reference substance during routine testing and research in environmental and chromatographic analysis.

Questions about PCB 127, ROTI®Star, 5 mg, glass
What is this article?
PCB 127, 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.
