Description
PCB 185 is a heptachlorobiphenyl analytical standard from the ROTI®Star range, provided as a neat solid for chromatography and environmental testing. It carries CAS number 52712-05-7, empirical formula C₁₂H₃Cl₇ and a molar mass of 395,32 g/mol, with EG number 690-259-1. Packed as 5 mg in glass, the congener is intended for gas chromatography applications such as calibration, system suitability checks and congener-resolved quantification of polychlorinated biphenyls. Environmental, food and industrial laboratories that track persistent organic pollutants can use this defined material within established GC methods. Offered by manufacturer Carl ROTH in the ROTI®Star portfolio, PCB 185 supports work that requires individual PCB identity rather than mixed technical formulations. The small glass unit is practical for preparing working standards and quality-control solutions while remaining aligned with the stated CAS, formula and molar-mass data for documentation and method records.
This article belongs on ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about PCB 185, ROTI®Star, 5 mg, glass
What is this article?
PCB 185, 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.
