Description

2,2',3,4,5-Pentachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a well-studied class of synthetic organic chemicals. This compound is primarily utilized as a critical reference standard and analytical standard for environmental monitoring, toxicological research, and regulatory compliance testing. It serves essential roles for research institutions, environmental testing laboratories, and chemical manufacturers involved in the analysis and remediation of persistent organic pollutants (POPs).

Application

• Environmental Analysis Reference Standard: Used for the calibration and quantification of PCB congeners in soil, water, sediment, and air samples via GC-MS or GC-ECD.
• Toxicological and Biomedical Research: Serves as a precise congener for studying the metabolic pathways, bioaccumulation, and specific toxic effects of PCBs.
• Food and Feed Safety Testing: Employed as an analytical standard to detect and measure PCB contamination levels in food chains to ensure regulatory compliance.
• Quality Control and Method Development: Essential for validating analytical methods, ensuring accuracy, and maintaining quality assurance protocols in testing laboratories.
• Regulatory Compliance and Proficiency Testing: Used by agencies and commercial labs to verify testing procedures against international standards for POPs monitoring.
• Material and Waste Characterization: Applied in the analysis of industrial wastes, transformer oils, and other materials for PCB fingerprinting and source identification.

Quality Control

Every batch of our 2,2',3,4,5-Pentachlorobiphenyl is produced and handled under strict quality protocols to ensure the highest purity and lot-to-lot consistency required for analytical applications. Our products undergo rigorous quality testing, including chromatographic purity verification, to ensure compliance with industry standards. A comprehensive Certificate of Analysis (COA) detailing identity, purity, and chromatographic data is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (typically 15-25°C). Keep away from strong acids and organic solvents. For long-term stability, consider storage under inert atmosphere at lower temperatures (e.g., -20°C).
