Description

2,3,3',4,5-Pentachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a class of synthetic organic chemicals. This compound is primarily utilized as a critical analytical reference standard for environmental monitoring, toxicological research, and regulatory compliance testing. It serves essential roles for research laboratories, environmental testing facilities, and chemical manufacturers engaged in the analysis and study 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 standard in studies investigating the metabolism, pharmacokinetics, and chronic health effects of specific PCB congeners.
• Food and Feed Safety Testing: Employed as a calibration standard in the analysis of PCB residues to ensure compliance with international food safety regulations.
• Quality Control and Method Development: Essential for validating analytical methods, establishing detection limits, and ensuring the accuracy of testing protocols in commercial and regulatory labs.
• Regulatory Compliance and Monitoring: Used by government and third-party agencies to monitor industrial emissions and environmental contamination levels against global POPs treaties.
• Forensic Environmental Chemistry: Acts as a marker congener in source identification and environmental fate studies of PCB mixtures.

Quality Control

Every batch of our 2,3,3',4,5-Pentachlorobiphenyl is manufactured and handled under strict quality protocols to ensure high purity and lot-to-lot consistency, critical for reliable analytical results. Identity and purity are confirmed via multiple orthogonal techniques including GC-MS, HPLC, and NMR. A comprehensive Certificate of Analysis (COA) detailing purity, chromatographic data, and storage conditions is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). The product is stable under these conditions but should be kept away from strong acids and organic solvents. For long-term storage, consider storage under an inert atmosphere to prevent potential degradation.
