PCB 34, ROTI®Star, 5 mg, glass

PCB 34 is a trichlorinated biphenyl reference standard from the ROTI®Star series, intended for chromatography and environmental analysis. It is registered under CAS number 37680-68-5, with empirical formula C₁₂H₇Cl₃ and molar mass 257,54 g/mol (EG nr. 690-193-3). Packaged as 5 mg in glass, the neat solid is practical for preparing calibration stocks, working standards and quality-control spikes used in gas-chromatographic PCB determination. Individual congeners such as PCB 34 enable laboratories to assess separation performance, assign peaks unambiguously and quantify residues in environmental samples including soils, sediments, waters and biological tissues. The material comes from manufacturer Carl ROTH as part of the ROTI®Star portfolio, which is commonly specified for GC and GC-MS applications that demand well-defined single PCB standards. Analysts can dissolve the solid in appropriate organic solvents and combine it with other congeners to build custom multi-component mixes. This presentation supports reproducible gravimetric preparation and helps maintain traceability in routine monitoring and method-development work.
