Description
PCB 175 is an individual polychlorinated biphenyl congener presented as ROTI®Star material for precise analytical applications. Identified by CAS number 40186-70-7, it has the empirical formula C₁₂H₃Cl₇, a molar mass of 395,32 g/mol and EG number 690-162-4. As a heptachlorinated biphenyl, this congener supports calibration, spiking and identity confirmation in gas-chromatographic methods used for environmental residue analysis. The 5 mg glass pack provides a practical quantity for preparing concentrated stocks and diluted working solutions in chromatography laboratories. It fits workflows that require discrete PCB isomers rather than technical mixtures, enabling clearer peak assignment and quantitative control. Environmental testing, method validation and research groups can use the material when building or verifying multi-congener panels. Supplied from manufacturer Carl ROTH in the ROTI®Star series, PCB 175 offers a clearly specified solid reference point for routine and specialised GC-based PCB determinations while remaining straightforward to integrate into existing standard-preparation protocols.
This article is part of ICP, AAS & ion standards, in Analytical standards & reference materials.

Questions about PCB 175, ROTI®Star, 5 mg, glass
What is this article?
PCB 175, 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.
