2,2’,5,5’-Tetrachloro-1,1’-biphenyl

PCB 52 (CAS 35693-99-3) reference standard from WITEGA Laboratorien Berlin-Adlershof GmbH serves as an environmental contaminant analytical standard for precise LC-MS/MS and GC-MS work. This polychlorinated biphenyl congener reference material supports congener-specific quantification and fits a chlorinated biphenyl calibration solution workflow in routine testing. Produced and distributed by WITEGA Laboratorien Berlin-Adlershof GmbH, it delivers consistent, traceable results from screening to confirmation.

Use this reference standard to build calibration curves, verify instrument response, and strengthen method validation. It supports confirmatory analysis with selected ion monitoring or MRM transitions and enables robust traceability. LC-MS/MS and GC-MS assays benefit from clean response and lot-to-lot consistency, backed by comprehensive documentation to maintain data integrity.

• High-purity reference standard with lot-specific data and full traceability.
• Optimized for calibration, quality control checks, method validation, and confirmatory analysis.
• Suitable for regulated laboratories, pharmaceutical research, residue control, metabolism studies, and multi-residue method development.

Regulated laboratories implement this material for daily system suitability and for confirmation at decision limits. Pharmaceutical research applies it to metabolism and fate studies of chlorinated biphenyls. Residue control programs deploy targeted transitions for confident identification and quantification. Multi-residue method development uses the reference standard to optimize extraction, cleanup, and chromatographic separation while assuring rugged performance.

Each batch includes a certificate of analysis with purity, identity, and uncertainty information to support traceability. Clear storage recommendations help preserve stability. When needed, matrix-matched calibrants can be prepared using the PCB 52 (CAS 35693-99-3) reference standard to verify recovery, linearity, and precision across instruments and laboratories.
