Description
PCB 25 is a trichlorobiphenyl reference substance supplied in the ROTI®Star grade for environmental analysis and gas chromatography. It is defined by CAS number 55712-37-3, empirical formula C₁₂H₇Cl₃ and a molar mass of 257,54 g/mol, enabling reliable identification and quantification of this specific congener. Delivered as 10 mg in glass, the pack size is convenient for preparing stock solutions, calibration standards and control samples. Laboratories use the material in residue monitoring, method development and quality-assurance schemes that require discrete PCB congeners. The product comes from manufacturer Carl ROTH as part of the ROTI®Star assortment, supporting consistent analytical performance. Clear chemical identity together with compact glass packaging makes it suitable for reference libraries, proficiency testing and routine GC screening of polychlorinated biphenyls in environmental matrices.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about PCB 25, ROTI®Star, 10 mg, glass
What is this article?
PCB 25, 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.
