Description

2,2',4,5,5'-Pentachlorobiphenyl is a specific congener of polychlorinated biphenyls (PCBs), a class of synthetic organic chemicals. This high-purity reference standard is critical for analytical research, environmental monitoring, and regulatory compliance testing. It is primarily utilized by analytical laboratories, environmental agencies, and research institutions involved in the identification and quantification of persistent organic pollutants (POPs).

Application

• Analytical Reference Standard: Primary use as a certified standard for the calibration of GC-MS, HPLC, and other analytical instruments.
• Environmental Analysis: Detection and quantification of PCB congeners in soil, water, sediment, and air samples for environmental impact studies.
• Food Safety Testing: Used in methods to analyze PCB contamination in food products, animal feed, and edible oils.
• Toxicological Research: Serves as a pure substance for studying the biochemical pathways, toxicity, and environmental persistence of specific PCB congeners.
• Regulatory Compliance: Essential for laboratories performing tests to ensure compliance with international regulations like the Stockholm Convention on POPs, EPA methods, and REACH.
• Method Development & Validation: Key component in developing and validating new analytical methods for halogenated organic compounds.
• Quality Control/Assurance: Used as an internal standard or spike in quality control procedures to ensure accuracy and precision in analytical data.
