PCB 53, ROTI®Star, 25 mg, glass

PCB 53 is a defined polychlorinated biphenyl congener available as ROTI®Star reference material for laboratory applications. With CAS number 41464-41-9, empirical formula C₁₂H₆Cl₄ and a molar mass of 291,99 g/mol, it offers a clear tetrachlorobiphenyl identity for calibration, identification and quantitative GC work. Environmental analysis and gas-chromatography laboratories use individual congeners such as PCB 53 to construct calibration series, verify peak assignment and support method validation when profiling PCB residues. The product is supplied as 25 mg in glass, a pack size that accommodates multiple stock preparations, long-term method programmes and shared laboratory use. In monitoring and research contexts focused on persistent organic pollutants, PCB 53 helps laboratories anchor retention times and response factors within broader congener panels. This ROTI®Star material from manufacturer Carl ROTH is intended for professional analytical workflows that depend on chemically defined single-congener standards. Associated CAS, EG and formula data aid documentation and traceability across reports and standard operating procedures. PCB 53 is appropriate wherever a discrete tetrachlorobiphenyl reference is required for gas-chromatographic environmental determination and related quality-control tasks.
